Hi Dave
My wife found the pegs on the R3 terrible, her comment was she always felt like she was sliding forward and could not brace herself back with the pegs due to their position and ended up with cramps.
We looked at the floorboards but ended up getting the Rivco floorboards extenders and adapting them to keep the pegs. As per Scorp the boards were very expensive. She can now lock herself into position during heavy braking and is comfortable on long rides. I think she likes to be able to lock the heels of her boots onto the peg rather than having a flat board. Just our experience may be of help.
