My specs: Right handed stroker. Med Rev's (about 300 rpm) and med. ball speed. My PAP is 5 1/2" X 1/2" up.
I bought the NSane a couple of months ago based on good reviews from a couple different sources. This ball is 3" pin out, with 3 oz. top weight. I used MoRich's "control" drilling with a Pin to Pap of 4", and mass bias just below thumbhole. There is a small weighthole on the axis point.
My normal leagues are bowled on synthetic lanes, with a 39' low volume THS.
My overall experience with this ball has been pretty negative. With this drilling, I find very little ball reaction on this house shot. I felt like the ball was giving up axis rotation too fast, and just didn't have any reaction down lane. When I hit the pocket, the carry is poor. A lot of flat tens, which is what you would expect for a ball that is burning up too fast. Attributing the lack of reaction and hit to the low volume of oil in the heads, I have tried polish on top of the factory finish, with no luck. I have also tried playing a deeper line, and slower speed, again with little result. I have my best reaction with this ball if I really come around it, and develop a more 90 degree rotation release, and have had a decent reaction. But, this is not my normal release, and the ball is very sensitive to variations in release. If I throw it harder, the ball revs nice, but just goes straight.
I recently bowled in a tournament conducted on a 40' sport condition, with heavy oil in the heads. I thought this ball might work well on this condition, with the heavy head oil, but again I found just a general inconsistent reaction and extreme sensitivity to my release. If I slowed speed way down, I was able to get a nice back end reaction--sometimes. If I missed the bottom a little, or didn't come out completely clean, the shot had no chance. Some of that was the sport condition, but I was able to switch to other equipment and get away from that degree of sensitivity.
I usually play around with this ball in warm up, and maybe the first game of league, just to see if I can get something going with it, but almost always put it away. By comparison, I use a Cell Pearl on this house shot, and the ball is a complete monster.
I'll probably plug this ball and try a different drilling. I hate to spend $$$ on a ball, and not be able to use it, but I'm afraid this ball may be in that category for me.
