yes the balls do react the same, but isn't that what u need for when u get a different condition if the lanes are really dry u think I'm going to bowl my widow or no mercy? thats were the blue vibe comes into effect and so on

if u think i have the balls drilled to do the same then u so very wrong they are  drilled to have the same shape but for different conditions after bowling for 36 years surely u must know the differences like that?

and how can u know if the lanes are easy or not when u don't know what anybody in the center score or what condition is on the lane

I'm taking from your comments youtr that good you have won some pba titles?
because if you want hard lanes then lets see how u do then

and your 300s was u saying easy lanes on those days i think not

before u make comments make sure there worth saying if not don't post!!

I practice during the day after the leagues and open bowlers have blown up the shot. If all yuo can practice on is a wall, try not to strike, just work on your release or foot work. Do not just go and strike, you will learn nothing.
