I have been evaluating the same boards, well maybe the Titan over the F1-R, but same dilemna. I wear a 11.5(US) boot. I always ride a wide board, partly for my 250 lb weight. My current board is a Gnu Rider's Choice 164 Wide with a 26.8 waist. I ride 0/+15. At 0, I have definite overhang, but I have never had any drag. I'd like to consider a non-wide board like the F1-R or Titan, but am afraid I need to go for the Titan TX wide instead. Also, the wides accommodate us fatties. What do you all think?
