Dude, I recommended against concave decks from experience.
You are free to make as many boards as you want with concave decks.
This forum is for advice, don’t get defensive if someone has experience that backs contrary design concepts to yours.
You are free to shape anything you want!
BTW, I started shaping concave decks for the author of Essential Surfing.
Hey all out there,
I think the concept is interesting and also has its drawbacks. It could be possible to glue a deck grip with similar specifications in order to get the same response without weakening the board.
sorry I wasn’t trying to attack you or anything, just thoughts about how to get around the drawbacks you stated.
