I rock a G-Suit, and am not that good in the park at all. I can do 360s, 540s, backflips and misties and a few more things onto an airbag, rails are hard, boxes are generally fine. But I REALLY want to get better, only I keep injuring myself!!
I love park skiing, I love watching it and filming it too. at the moment I have to cruise through the park jealous of everyone throwing down and hoping to put a good edit together at the end.
So I guess what I am saying is, most people who dress steezy are probably keen to get good even if they aren't already.
But I also agree that you shouldn't claim it if you can't do it.
