Ball is 15#, 4" pin, unknown top weight (got it used). See my profile for personal stats.
Drilled 5.5 x 5.5 (pin above, a little to the left of middle finger), CG more or less stacked below. Light coat of polish applied.
I normally throw on two different sets of synthetic lanes. #1 has 36' of oil with a fair amount of carry down. #2 has 40' of oil, fairly clean backends. The Purple Pro does better on the longer pattern with the cleaner backends. The drilling, surface, and low flare of the ball needs some dry to get into a nice heavy roll.
This ball does next to nothing in oil, but knows what to do with the dry when it finds it. I don't have the hand, but I don't think much of anyone could make this ball snap. When it finds the dry part of the lane, it makes a hard arc for the pocket. The hitting power is deceptive. It won't blow the rack apart or send many messengers, but a good hit will be rewarded with a strike. Many times people will watch the ball roll and think "flat 10", only to have it kick out the 6 anyway. Along with my other Buzzsaw (Pearl Cherry C2), I seem to leave a few too many 7-10's in the hole.
The Purple Pro also gives great release feedback. Throw it flat and watch it go straight. Juice it too much and crush the nose. Forgiveness around the pocket is also very good. Light hits carry way above average. The worst you will leave on a slightly high hit is a 4 (probably because it is rolling, not snapping). The ball reacts better when I come around the side a bit. If I come straight up the back, it will go very straight. I use this ball and release for my 10 pins. I retired my Blue Dot because my conversions with the Purple Pro were higher.
I haven't got to throw it on a truely dry condition to see what kind of length it would get, but I don't think it would be a problem.
Added 5/10/02
I am in the middle or redoing my arsenal and decided to change the cover. Had the proshop put it on the Haus machine a few minutes to dull the cover down to around 1000 grit (no polish). The ball now reads the midlane much better. It makes it's move a little earlier, but still maintains the hard roll/arc like before. Makes the reaction a lot more reliable. I no longer have to worry if the ball will find enough dry to turn the corner.
