...Easter that is.
Whatever other mumbo jumbo you've heard about the Sarge Easter grip, I tried it out due to recurring pain in my ring finger, and for that it did wonders.
Other than the pain issue... I had trouble revving the ball for about a game til I got used to it, after which I had no problems creating as many revolutions as with a normal finger tip grip; It didn't seem to change my axis rotation much, but it did change my tilt a tad, I haven't measured it, but my track has migrated about 3/4 of an inch away from my grip.
Those were the most notable changes so far, I'm planning on tinkering with the pitchs and layout a bit. I'll post again if I find anything interesting.
