Once again, Roto Grip® continues to move to the forefront with the introduction of the all-new Mercurytm.

The Mercurytm is an entry level ball energized by the newly designed Orbitertm core. This high RG / low differential weight block delivers increased rev rate in the mid-lane along with smooth continuation down the lane.

Encapsulating this new power plant is the always successful Sure Grip IItm pearlized reactive coverstock. This mild reactive blend gives you fluid acceleration through the heads and dependable backend motion through the pins.

Review:  Great dry lanes ball.  By far the weakest resin ball out there that carries everything!  I hit light,heavy,bury it it dont matter it carries it all.  Never seen anything like the carry it not very impressive alot but they all fall down somehow only down sides are i dont get to use that often and it dont like alot of carry down.  I have since replaced it in the bag with a condition specific saturn, but I still have this gem no way i would ever sell this one.  It is a great ball. For the price it is wonderfull a must buy.  It is out of this world.  a solid 8 out of 10.  Keep up the great work roto!!

Boy do I love bowling, stone 8,stone 9, ringer 7,fly by 10,fast six got to love this game.  Short look at what most of my games look like with a few strikes peppered in between.  Isn't it wonderful.

First RotoGrip ball, and  very impressed by the reaction. Fingers drilled above the pin with the CG maxed to the right and a x hole. The lanes were very spotty withoutside hang out of 5. Keeping it inside of this was fine but I had to keep the speed up. Getoutside of this could lead to washouts or gutters. The direction of change is very precise. After 40 feet it jolts but not a violent backend. It can be a great dry lane ball, yet I still had to cover a lot of boards with it. I was only disappointed about the total amount of hook thinking it would be a little less but with the CG placed where it is  this may be because of it.  The ball keeps the pins low and an average hitting ball. I did leave a lot of 9’s with it.
In league on a little heavier pattern it played very nice. A good benchmark ball for medium to dry lanes. I’m impressed with this ball and may get another Rotogrip ball for heavier conditions soon.

Any company can make a weak ball that gives you length .. but getting it to have length AND roll up nicely AND hook consistantly AND carry .. theres a little more to that.

I was fed up with entry level balls looping down the lane and either jumping on the backend or never actually hooking (I know you've been there). The Merc for me rolls more like a lower RG ball, always inspires confidence to see a ball roll nicely and hook consistantly. It really is different in this respect.

The fact that the core appears to have been properly researched, designed and tested rather than just throwing a puck into a spareball core, and because of this the Merc (and Saturn and Venus too) raise themselves above other entry level balls, and continue in the vain of the previously impressive Sonic line. They're not so much entry level, as High Performance Light Oil equipment.

The Merc's cover is mellow. It will hook off dry boards, but when it does its smOOOOOOOOOth, with lots of capital O's. Probably the mellowest reactive I've ever thrown, so if thats what your after you can stop looking now (I mean dont even read the last paragraph, just go out and get one now!).

Even drilled strong its smooth. If you want more backend action, a leverage pin will still give length, then drill the cg/mb for a strong reaction and utilise a balance hole to increase overall differential.

Perfect ball for shooting 3-6-9-10's I might add, never missed on when I've tried with the Merc.

14 # ball with a one inch pin and 2.7 oz of topweight before drilling.
Cg between fingers pin above bridge. This pin is just a hair from my inverted track.

I'm a no-thumb bowler who is averaging between 193-219 in various houses.

I usually use a Sonic X with a 5.5 pin to pap and a 4000 abralon finish with no polish on fresh lanes. The X gives me great control of the midlane and exellent hit when head oil is present. However, when the lanes get toasty the X gets jumpy and hard to control. I have been looking for a ball to fit under the X for 2 or 3 years. I have tried the dry heat, big hit, scout urethane high flare, slate blue gargoyle, power groove dry/r, and others without success. This brings us to the Mercury.

I had this drilled up a few weeks ago and had really been unable to throw it. The ball went dead straight like plastic when I tried it on various house shots. This was very encouraging because all of the other balls mentioned were strong enough to play on fresh oil.

I finally found lanes too dry for my Sonic X and tried the Mercury. I was actually able to move out to the track area and play really straight. As long as I kept my speed firm I was able to stay out of trouble and string strikes here and there.

For a player like me who hates dry lanes, this ball is a life saver! I was able to outscore everyone on the pair on what is usually a condition that makes me cry.

If you have hand and need a ball to clear burnt heads and then not over react on the backend, the Mercury is an excellent choice. I think I have Finally filled this spot in my bag.

If you are looking for an entry level ball, the Mercury is probably too mild for most bowlers. Go for something stronger.

A great ball on dry lanes!

For everyone reading this.... If you have slower ball speeds or more revs than speed then this is the dream ball for you! I drilled mine with the pin slightly above my two fingers and the cg about a half inch from thumb and straight over the palm..... My PAP is 3 3/8 over and 1 5/8 up.....

Just because this ball is meant or designed for dry lanes dont mean they have to be dry to use it! The coverstock clears the heads so amazingly that you wont believe it! I just recently bought 7 roto-grip balls and this ball is by far my favorite of the 7!!! Every bowler needs this ball and I really mean that. This is the most under-rated mid priced ball EVER!

I would rate this ball a perfect 10 because if this ball wont turn the corner hard enough on certain conditions then you could allways use it as a spare ball!!!!!! Truely amazing piece of equipment and you better get one while you still can!!! John

This is my first Roto Grip purchase. Got it from bowlingball.com, based on the reviews I've read here. I had it drilled for length, and picked it up tonight (March 25) on my way to my late scratch league.

I threw my Legends World Class on an inside line (sliding at 25 to 15 at the arrows to about 7 at the breakpoint) for the first two games. First game was 213, second game was on pace to be in the 220's, but then disaster--my line just disintegrated, even with a move and added ball speed, and I got 3 big splits in the last 4 frames to end up with only a 181. I figured I'd give this ball a shot.

Played down and in up the 8 board with a little less hand and a bit more speed than I was using on my inside line. Left a couple of 10 pins before fine-tuning the line and release, and rolled a 216 when most everyone else was struggling to break a deuce.

This is a great ball for fried lanes. Very controllable and predictable, and hits fairly hard with pretty good carry. I'm glad I got it.
