I ride a 157.5 2011 riders choice and absolutely love it--it's a fantastic all-around board that does it all. I bought it brand new last March for $350, marked down from over $500, so $300 seems like the right price. As far as size, I'm 6' 190lbs and the 157.5 is good for me. I imagine the 151.5 would work nicely for you. Enjoy!
