Don't do it. You'll snap it on your first session. I tried this years ago on a shortboard I'd had for a while. I routed out a small area of the deck, added inserts imbedded in an epoxy slurry, and laid a small glass patch over the whole thing (probably like 3" square). I launched a small jump off a boat wake (no more than 2' high or so) and it snapped like a twig when I landed on another wave, broke right between my feet. You can apply so much more force with the straps... nevermind you're already pushing your luck using a surf specific board.
oh really ?!... damn so you'd recommend just using the deck grip and see how i like it without straps?
it's quite an old board too soo i'm worried about it's strength
