I like my widow at,500 grit,2000 grit,4000 grit.I can't seem to find a happy medium because the ball acts so different with the different surfaces so,... I got a no mercy.diffrent ball,different drill and I'll have a different surface on it.I hope I'm correct in my thinking.I think I am but until I get the ball and find the surface I like on it's merely speculation.the safe bet would be to get another widow.I've also noticed my widow works great with allot of axis rotation but it's not a rip the cover off type of ball.smooth release is the only thing that works with the widow,maybe the no mercy is the same way and that's why you see so many mixed opinions on the ball.
