I have had good luck with Roto Grand Illusion and Venus. Have been needing to get a ball for drier lane conditions. Have the opportunity to pick up Mercury real reasonable. Just looking for some opinions if anyone could help.
Thanks,
Mark

Love mine, but it isn't a "weak" ball. Expect a good move when it hits the "drier".

220...221...whatever it takes.

I agree with lefty. Great ball for drier shots, but it will usually make a jump once it finds some friction. Our shop sold several of them, as well as the newer version, the Neptune.

Had two of these. Will get thru the heads great but expect a "very" strong move on the back. Can be very flippy so be prepared to tinker with the cover to even it out some.

Understood that you can pick up a Mercury, but if you are looking for a step down get a Neptune. The Mercury and Neptune are essentialy the same ball but with the core inverted on the Neptune. Drilled the same way as a Mercury it is smoother off the breakpoint - a better drier lane ball IMO.

I think his statement that everything is the same except the core is inversted could be true.
Or does it require different densities to get that diff differential.....?
Not sure.....could someone from Roto weigh in?

i'll chime in on the one. I have had my mercury for almost a year now. it is drilled 5x4 pin up with a 4000 abralon surface prep. it has been a saving grace for me when the lanes start to dry up and my secret agent or venus become too much ball. I have even had alot of success using it on a fresh house pattern playing straight up the five board. i agree with cooksey that the ball can be flippy with the oob surface, and i have that a 4000 abralon surface is perfect for me.

Comparing my Neptune to my Mercury:
Mercury was drilled pin down with the CG kicked right a little and it was smooth down the lane. Very easy to use on light oils, not jumpy or angular just a smooth rolling predictable ball.
Neptune was drilled pin over ring over the CG and this ball was over under city. It hated any oil and any dry but played well on short oil as long as the backend friction held up.
For me the Mercury was a far better light oil ball.

The differential difference is based on the core being inverted.
Same cover - both are Sure Grip II Pearl Reactive
Both are designed to be lighter oil balls. For me, the Mercury is jumpier off the dry and I prefer the smooth movement of the Neptune.
I'd also agree with Gabriel for both of these balls. The Sure Grip Pearl surface is better at 4000 than box. At box it is too over/under.

i had a mercury last year in college tournys and never had a trouble getting the ball to the pocket even on the driest lane conditions and the most broken down heads. It is a perfect weaker ball that will fit into your arsenal and i would get it if u still can. It was never flippy for me but it was drilled 6 inches from my pap so i wasnt expecting that kind of reaction
