The specifications of the Stinger 2 Piece are: Factory Finish: Factory polished Detonator Plus reactive resin; Color: Red and Royal pearl; Core Shape: Large single density ellipse; RG Rating (actual): 2.53 (16 lb.), 2.57 (15 lb.), 2.63 (14 lb.); Differential (actual): .052 (16 lb.) .044 (15 lb.) .039 (14 lb.); Length: scale 1 to 10 (early to late) with factory finish: 7.2; Backend: scale 1 to 10 (least to most): 8.1; Overall Hook: scale 1 to 23 (least to most) dull/shiny: 17.7 dull/10.7 shiny; Hook Style: Clean through fronts with medium backend hook.

Drilled with the pin over the ring finger, cg in the palm, no extra hole.  Polished the cover with Factory Finish to get some length on drier conditions.  This is another very versatile ball from Ebonite.  The cover is fully adjustable depending on your needs and the hit is excellent.  I tend to use this when my Vortex 2 is burning up a little early.  The higher rg core and polished cover gets it down the lane with a nice hard arc to the pocket.  For the money, you will not find a better all-purpose ball.

PART #1 - SOLID

this is a good ball. used it dull first and got a smooth earlier roll.
even worked on some oil. tried it on wood an synthetic and got excellent reaction and hit on both.
polsihed a bit(around 1000) and it got up the lanes better, but still hooked.
still works on oil, but you have to be careful not to over throw it.
has more backend polished than dull with same results on the score sheet.

excellent control ball on most conditions. havent used it on a tournament shot yet.
i rate this ball a 9 of 10(especially for the price)!!!!

drilled it close to 3 3/8 leverage

dont let this ball fool you.. its an aggressive ball. more than i anticipated

I got this ball free from my friend. I have this ball drilled for a lefty. PP about 1/2 inch under the ring finger and cg about an inch down. This ball is much better than I thought it would be. I first used it on my dad's desert dry house lanes and didn't to to well. The ball would come in way high and leave a lot of splits. I took it back to my synthetic house lanes for my thursday high school league and shot 231,205,and 226. I would recommend this ball for med oil. If you're looking for a late reactor for real dry lanes, go for the bvp punisher or the ice.
