I am looking to buy a new board, the Arbor Cadence. However, I'm not sure what size to get and I wanted to see if anyone out there has tested them out! I am 5'7" and 105lbs. and I am hemming and hawing between the 143 and the 147. I'm concerned my height to weight ratio might make the 143 feel a little short. And Arbor's weight guidelines for the board are super broad. Any help??
