It always amazes me when bowlers take balls designed to hook and drill them to hook less or polish them to go straighter. We design product lines like the Vendetta line so as to give the proper performance on a wide variety of conditions. The Sniper was not designed to be polished. It was designed for heavier conditions and carrydown. If a snapping finish is desired than the Pearl or the Black Vendetta are the balls of choice.
I'm certain that 90% of the bowlers on this site have at least 3 balls, yet i'm just as certain that the same bowlers end up with similar reactions from each of the balls after they do their tweaking, polishing and sandings, not to mention drillings. Remember not all balls work on all conditions. Especially in todays environment.
Bowlers should learn a valuable lesson. The manufactures for the most part are the experts and if a ball is sold with a dull surface on it there is a good chance that it will perform best in a dull state and on a specific condition. By changing the surface dramatically you risk the chance of making it perform like a product you already have or it may not perform at all.
We at D/T design arsenals if you need less hook we sell it in that line, best advice I can give is to leave it in box condition or sightly tweak it, use our suggested maintenance programs (not the one you think is best).
One of my favorite expressions is " Just because you hang out at an auto repair shop that doesn't make you a mechanic"
