Description:
In today's Fast-paced and High Scoring environment your equipment must have the technology and horsepower to stay ahead of the competition. Roto-Grip has delivered once again with the introduction of the Rush.

The Rush is powered by an all new Hemispherical-"Hemi" core. This low RG/medium differential "Hemi" produces increased spin rate for earlier mid-lane traction with continuous acceleration to the finish line.

The tread on the Rush consists of an all new Posi-Trac solid reactive coverstock designed for added traction and continuous backend motion.

Specifications:
Color Purple/Yellow
Coverstock Reactive
Core 2-piece Asymmetrical
RG 2.47
Differential 0.043
Factory finish 1000 grit matte
Weights 12 thru 16lbs
Lane Conditions Medium-Heavy Oil

15 lb  w/ 3" pin
Drilled 3 3/8 X3 3/8
Shined to 800.

I would classify myself as a power stroker with medium speed and medium/high revs.

I love this ball on Oily or Medium lanes. Reads the lanes easily and has a strong but smooth backend. I can't get inside with this one. It is very playable from 15 to the ditch, but the line has to be somewhat tight. It doesn't seem to hit very well if I swing it out more than 5 or 6 boards.
As long as there is oil in the heads, I can move right with this ball and it carries all day. It is normally my first ball out of the back for league.

16# ...box condition, 4x3, pin next to and just above ring...cg at midline kicked out.......small weight hole just under pap .....

WOW is this ball ugly....but oh...she's soooooo sweet!!

Throw this ball and it'll tell you EXACTLY where it's going EVERY time !

Medium -medium heavy arcing ball, with a smooth transition off the dry boards and a midlane read that's perfect....and when she turns the corner (as posted by many others) it looks like it's going down hill!

Easily controlled, easy to read, great hit...hell, ...low rg strong arcing solid ..what else could you ask for!

I found succes with this ball on both wood lanes and synthetics...with the wood house being a heavier pattern.....did't really matter with the Rush...it reads the pattern incredibly well and arcs till the cows come home !

I would consider this ball for league..especially if you want something that arcs, and definately a tournament ball to smooth out patterns, wet-drys and something stable!

The Rush is a BIG SLEEPER ...I'm hoping Roto Grip does something else with the Hemi core !

I think I'm finally starting to catch on.....
Proud FCC!

For what it's worth, my stats and video are in my profile.

My Rush is layed out with a 4" pin to PAD(pin axis distance) 1 1/4 inch above the midline with a strong X-hole in the thumb quadrant(6" 45 degrees from the center of grip).  OOB finish at the infamous "800 smooth" proved to be WAYYY too early of a continuous sweeping hook for oil volumes in 5 different houses that I bowl in.  The flare was 6 1/2 inches and my rings were almost an inch apart.  I took the cover down with a Burgandy scotch brite and applied a burned in coat of Brunswick Rough buff.  I wanted to still retain the quick revving in the midlane that this ball does by nature but just more push down the lane.  Rough Buff was the ticket!  I easily got about 6 more feet out of the ball and a very strong arc off the end of the patterns that I've thrown it on.  I've thrown hundreds of balls, but few have the strength of the Rush off the "spot" in a polished state.  The stength can definately be appreciated when you see how hard the ball finishes.  It's strong through the deck which keeps the pins very low which is a good thing.  A flat ten every now and then is usually the signal for me to put this ball up as it's using too much strength before the end of the pattern or I am trying to cover too many boards with it.  In med-heavy+ volumes and carrydown is where the Rush will shine for just about every style.

Imo this ball rivals overall strength and performance with something like a Vortex II, Nemesis/Wizard, and Diablo.  

For those that love low R.G. core systems, this is a ball versatile enough to put your favorite drilling/surface prep on and have a #1 ball out of the bag reaction.
