Depends on if you ride park or all mountain. For park go smaller, all mountain go bigger.

I mostly ride all mountain... I'm guessing the 154 would be the way to go then... I should still be able to slap this around the park tho right? I mean is there much difference btwn the 151 and the 154 in terms of stiffness? I'm not that big of a dude to begin with...Lemme know...

Exactly as they say... if your a park rat go 151... If you just dabble in the park and ride all over the mountain do the 154
