What's up everybody? I'm somewhat new to boarding and HOOKED!!! I used to ski til my work buddies took me out in 07' and caught on pretty quick. I picked up what I thought was a good board at the pawn shop for $50. It is a Burton Seven 51 with boombox graphics with some shitty kingpin bindings, but have since upgraded to a pair of 08' k2 sonic bindings. Now I'm short and kinda heavy at 5'4" and 175lbs, and I was wondering if this board suits me. Last year my board had a sloppy feel to it but the board was worn pretty bad (needed tune/wax) and the binding could only hold 2 of 3 screws that would loosen up a couple times a day. I also borrowed some pretty badass boards starting out with my favorite being a florscent yellow and green LibTech board. I know I babbled a bit but could you help me out?
