I have a softy standard with standard forwards. I'm a short arse and after a day out my right calf muscle screams from opperating the rear brake. With the floor boards you don't have to pivot your foot just lift and tromp. You can do with my oppiion what you wish , but I'd keep the boards if I were you.

I changed to forwards on my 08 Fatboy, much more comfortable on longer rides and much much less scraping.
I was also thinking of changing the boards to pegs but have decided to keep the boards. On long rides I move my feet about quite alot from forward to a bit back to middle etc. I believe that with pegs your feet will be stuck in that one position so floorboards for me have the advantage of having a bit more leg movement. Keep the boards is my opinion and learn to go a bit slower around bends.
