yesterday i was paracticing in a house shot where a pba member has troubles to throw 205 ave. and i was bowling really nice with my new classic zone...then they have to switch me to a house shot...can u believe that bowling the same line (of course with a lot more of margin)i shot 279-276-279
man now i understand what u guys talk about...i am a solid internantional 210 ave. but that lanes change was dramatically
and i was just practicing testing a new ball
