So I am interested in buying FR's and I found a pair for pretty cheap. Only problem is that I was looking for a 176, and these are 171. Currently, I am 5'7", but I would be buying these for next year and I am still growing. If I had to guess my height for next season I'd say 5'9" or 5'10". Now, I know ON3P runs a little long compared to other companies because they measure after pressing, but also feel shorter than they are because of the rocker. Do you think 171 would be too short? Thanks.
