hey dude, welcome,
my advice would be to ride the hell out of them, and then decide if they have enuf balls or handling for your type of riding and terrain, get a feel for how the bike is reacting to your riding style, do searches on here first, on info that you need, chances are theres already been a thread about most things you'd need to know, that way you can read them from start to finish and not have to wait for answers, then go from there and ask away
and you can post on all the threads here except buy and sell,
you need to have 300+ posts or pay the $10 to join for those
