last year i moved up from a 165 to a 180, and it was the best decision i have ever made, i am 6'1" and 170pounds, and it just feels so much better to ski something bigger, almost everything is easier, and it only took me about 2 runs to get used to the extra length. additionally, as previously stated, center mounting them will make them ski a little shorter, so you most definitely want to go longer if you plan on mounting near center
