Hasn't happened to me, but I did think this plasic (ESP) is differnt than ESP plastic I've had in the past. It does seem softer and seems to damage easier. Having said that, I like the new feel to it. It's more tacky and not as hard. Two reason why I never liked ESP plastic.
I got 2 nukes on the day of release and one of my hotstamps is pretty much gone too. THe other is lasting...I think only cause it is darker and I don't throw that one as much. But after the second day throwing these things they were disgusting looking. Disc absorbs dirt. They look like the oldest disc in my bag and are actually the newest. You should loosen your grip though man. I have done it recently and have gotten more distance...20ft or so. Plus you won't have to buy your disc from "Hulk Lab"
