I have ridden the SLR-R and found it to be a fun lively board. I haven't had a chance to get on the F1. Hopefully in a couple of weeks here I will demo it. As I am thinking of making that one my next split. If you are more freestyle oriented, I'd say go with the SL. If it's freeride big mountain stuff you like, I'm sure the F1 would be the better choice. Neversummer really doesn't make a bad board. The one you want is based on your tastes.
