I took the plunge, figured it was only $12.95. If it worked it worked and if it didn't it, well was only $12.95. Unlike the tri-grip i was happy to take the risk.
Anyway, even though I'm really happy with my current fit i found that the ball fitted a lot more comfortably in the hand and made my release feel a lot more effortless. Immediately i noticed that my speed and rev rate increased and even my track was slightly higher then before.
Straight off the bat I hit games of 225, 238 and 247, usually i average 210 in our house but shot execution seems to have improved. From what i can see, I'm impressed with his method.
I'm implementing it on a few more bowlers as I'm curious to see how it effects them.
If you're skeptical I'd say just go for it, you've got nothing to lose really.
