I have a 13 F6B with Mustang seat . Went on a 800 mile trip with wifey 3 weeks ago. Had to make a few extra rest stops for the wife to stretch out her legs but usually I can go tank to tank. The full wing is better for the passenger according to wifey as we have gone on 4 test rides on the new full wing. Myself I find the full wing a little cramped for me. She did like the Alaskan sheepskin seat pad I provided for her though.
