Question about pumping tranny.

A while ago I saw on here that when you are pumping going down the tranny ramp you should be driving through your downward foot (the foot that is leading). When ever I'm try this it feels much more natural and easier to balance to push down with my uphill foot (backfoot). Whenever I do push on my uphill foot sometimes it feels like the board will pop up on me as if I'm trying to do a manual.

Anyway so is there a correct foot to apply force through?
