Environment may play a factor in it as well. Call it weak will if you want, but if you're the only PLer in a gym full of BB types, you don't think you'll look over sometime and think, damn, those traps (or other) are insane, maybe someday I'll shift my focus for a little while...
I've got back envy. I'm a small guy, but I carry most of my BF as a spare tire. I'll probably never compete in a BB comp, but I would love to get some PL meets under my belt. That said, I secretly would like someone to envy the product of my hard work, and the aesthetic results require no bragging.
