I love mine when I can throw it. I agree with alot of what has already been said. I am a stroker, 16mph. I drilled mine 60x5"x45 which puts the pin just above my ring finger. It is a very strong ball but it gives me a reaction and a roll that i have been missing in my bag for awhile. But as one reviewer said and I have learned since getting the ball, you HAVE to know when to put it away because it is so strong.
