Ok, so I only recently got the hang of surfing but I feel like I'm about to start advancing really fast. Now I have two questions to ask.
1. The board I'm riding is 6'0" and I'm about 5'7" and 135 pounds. With it being oversized will I be able to properly utilize the contour, rocker of the board, etc.? Or should I not worry about that stuff just yet?
2. Since the board has more volume than I probably actually need, does that mean I can ride it in bigger waves? Oh, and it's a DHD Scalpel. i think it's supposed to be for like 1-4 foot waves.
it's probably fine. just worry about catching as many waves as possible, getting in early and trying to go fast. good body mechanics just pumping down the line (at your stage) are the foundation for everything else.
if you do want another board... im in your area and have way to many boards. i have a 5'5 you'd like. easy to surf and light as sh!t. pm me.
HSS: Sick with the board you have while you are still learning the basics. Having a slightly bigger board can be like swinging a weighted bat--and it's not like that board is grossly oversized for you or anything.
...or basically what AtanticO said. Plus a larger board can help you with learning how to keep your momentum through cutbacks.
