Well I swapped the washers over today and the foot mounts are much better.
Having said that I can feel a few extra vibes through the balls of my feet but when resting on the instep of my boots I cant feel them.
I'm gonna leave them flipped for now as I think having more rigid foot mounts is worth the odd vibration.. Will have to get out and do a few miles to see how I get on..
thanks again.. great tip...
