Considering I know absolutely nothing about your riding style, your weight, height, ability, location of mountain, I can't tell you shit.
With that said the people who said the WWW have a good idea for a good park board. But you sure as hell don't need a $350 board if you're just starting out. They have entry level/intermediate boards for a reason.
Lastly, don't listen to the haters saying that you shouldn't come to NS for questions even if it isn't skiing related. We love all people in the industry. And as long as you're sliding down a hill of snow, I'm cool with you.
Cheers
p.s. Gear Talk next time homie
