Duke, thanks for your thoughts, not sure if the logos are in the same place or not, I think they might be. That's as far forward as I can go with the (mono) strap set up.
I did get the lift foil going faster down wind on the third session.
Looks like its time to man up and lose the strap. (my history is around 5 years on a strapless directional).
I have noticed in most slingshot clips there team riders front foot seems to be further up the board.
Here's a pic of the board I think mine is further forward.
Cheers
Grant
