Those new x plastic ones wear more similar to KC Pro, I've been crunching one on trees for a few months, still fades at the end but its getting some turn. My truly understable mid is one of the older x plastic buzzzs, feels a little chalkier and is a little flatter/doesnt have a high shoulder. Great turnover disc, still needs some power behind it to keep it turning right until the finish. Doesn't really flip like a fuse or comet, but I dig it that way. I can throw it a lot harder and farther than either of those two discs and I just use a beat wizard for that shot now.
