Scaffolder, mind if I ask your physical dimensions? Height, inseam, etc? I'm considering the FJR/C14 option when I trade up, too. Ikn've got rises on the C-10, Kneesavers, Corbin seat w/Airhawk and it all works pretty well. I've sat on each and the C-14 seems to fit more "naturally" as it comes from the factory, if you know what I mean.
For comparison - I'm 6'4", 35 inseam, #13 boot, 250# weight, 18-36" shirt size (2XL).
Thanks and sorry to hear it didn't work out for you.
