Anyways, give a holler back when you get the pedal, to see how you're getting on with it.
I kinda expect that sideways motion with the foot to be honest - you'd get that with a chain too. I have an OLD tama chain pedal that moves loads unless you strike straight.
Fingers crossed it'll be here early next week so I can give it a good run before my plethora of gigs in June!
