OK! You guys are very helpful, thank s a lot!

First of all, KWPBA, I'll go and ask if they actually "shimmed" the gutters to compensate for the raised deck.

I am not actually having a "carry" issue other than more 10 pins than before. Sometimes like 3 in a row. I actually talked to a guy in my league who does a much better job at carrying the 10( but his ball is 2 pounds heavier) and he told me to "keep the hand below the ball more". He said that would make the ball go a little longer before making the turn and retain more energy. He said my hand rotated too far to the top of the ball. I tried that and it seemed to help at least 50%.

The same guy also told me a university conducted a study by increasing and decreasing the gutter depth by 1/2 inch. The result was something like a 23 pins difference( among bowlers with 185 to 195 average, as far as I can remember). Again, this is just something that I was told.

Of course it's mostly operator error and of course the "best" is to practice until I can make a "dead flush" hit every shot. I don't mean to "depend" on a pin jumping up to trip the 10. But to bowl a perfect game quite often you have to get "some" help............a "perfect" game does not mean 12 "perfect" shots, does it?

Anyway, thanks again everyone!
