Please tell me you aren't still running your handlebars Chicago style? (forward)
Handlebars should be between straight up and down to the angle that your forks are at which is typically about 75 degrees or so (less actually). So, somewhere in there find a comfortable position and your tricks will come much easier.
La-de-dah - nice pics, looks like you guys are having fun.
Lots of G-N-R stuff is good, some of it is just to blech for my liking, but they managed a lot more likeable songs for me than... let's say, Red Hot Chilli Peppers.
I don't really like any bands, or dislike any bands... I like music and songs, one by one.
