Could you measure the distance of the foil inserts (or edge of the base plate) to the back of you board.
This to compare with mine and to check if they are equal.
Maybe the foil should be more toward the back?
I have that setup and have the foot straps all the way forward for the front and back. Try moving your front ones forward. It would have bee nice to go forward even further I think, but thats where they ended up.
