156 K2 Eldorado board

hi guys. glad to meet you.
i need your help. i'm a about to make a bargain, or so i think.
i can buy a 156 eldorado board, almost new, for only 70 € (about 75 dollars i guess).
the point is that i weigh about 167 lbs and i'm 6.1 ft tall.
is the board ok for me or do i need e bigger one?
i don't like the park, i'm a free-rider who doesn't like to go too fast, but likes to do some little tricks on the ski run.

thanks for your suggestions
