over the past 2 years i have tried 4 different tips (Le pro, kamui blk ss, sniper & onyx) and settled on the sniper tip about 1 year ago....changed to an "onyx" tip and just wasn't as pleased as with the sniper. so i purchased another sniper tip in dec 2012.......after a month the tip has begun to glaze after one session of play. the other sniper never glazed over, that was one of the very reasons i liked it. so, did they change the process or what?
