I have an Acid with a strong drill 60 deg, 3 1/2 P2P, 30deg. For me (take a look at my profile) this Ball is very smooth and strong. Its the very edge that is still (for me) playable on Kegels Middle Road, it could handle more oil.
I also have Rico on a switch blade. The switch blade on 1000 grid compared to the Acid, reacts weaker and even smoother, its a very nice and unique reaction in my arsenal. The strike angle feels a bit strange. On 1500 Grid with polish the switch blade rolls to unpredictable for me. There are better balls in my bag for any condition than the switch blade, but i like the idea to have it with me on tournaments, it saves me more then once.
Hope this helps you somehow.

it's almost always the indian and not the arrow

don't go for a strike, go for a sure spare, we need 5 pins to win
