how much concave?
Im building a board and just seeing what the average preferance is. i dont think i know what i like yet as i havent really tried out many boards, but i think im more inclined to go steep. however as my last attempt turned out to have 1 1/4 inches i know i have to aim down. the middle of your foot doesnt even touch the board.
Does anyone know what the standard concave is on most boards, i know the 09 avengers about 1.5cm , but it has a pleasure dome.
suggestions?

Imagine you're cranking the deck over in a turn; the top pic shows convex; the bottom one shows concave. All your pressure is on the bottom rail, and you want the deck to stop your foot from slipping up over the the top rail. Which shape would hold your foot on better?
I think convex would would hold better cos it provides more of an angle for your foot to push against the bottom rail. Concave flattens out the angle at the bottom rail, making it easier for your foot to slide up and over the unpressured top rail.
Somebody should mount a concave deck upside down to test this wacky theory.

surfboards are convexed and they hold ya feet on (with abit of wax there) but if you used some nice rough tape it should work the same, if you stand on a surfboard you notice that they are not quite flat on top, i have seen a guy run a board upside down and then add some rails to the top

Youre theory is interesting bugs and there is no question that once cranked over the convex deck there would be more angle, but would this angle be too much and the contact patch of your heel or toes be too small resulting in slipping off the other way, down over the bottom rail?
Another thing to consider is a convex deck will be nowhere as responsive as a concave one as all your body weight has to be shifted to to that edge before it will turn. A concave deck will start to turn when you start to shift your weight.
There would certainly be times when convex could be a good thing but I think there is a reason why most decks are built with concave these days
