Sup & prone boards , kite board & boogie board 
Hey Piros,
how much rocker / concave did you have in the boards.
I was hoping to mount one onto a surfboard but it doesn't lay flat. would have to put a lot of pressure onto it make it stick to the board.
Worried that it might pop back up with the foil pressures.
Yeah good question, the plates are super stiff . If you force it down ( like standing on it ) on a concave or convex bottom the standard plate could delam your board. They bought out a new mount which is spilt down the middle to let the plate flex (see attached pic). The plate is still pretty stiff so if you can't push it on with your hands (before you peel the tape) don't fit it. They really do stick like sh!t to a blanket and won't let go but if you force it onto a deep concave or double concave or Vee it could pull the glass. If that's the case just lay up some glass to make it flat. They work best on production boards and not customs with single layer 6 oz or less on the bottom.

Can't believe the dude in the video just wasted an awesome board with that crappy sticky thingy.
As he mentioned the cost this thing is about the same as getting inserts fitted by a shaper (which allows to use the board as a surfboard too).
I'm the dude and you can peel them off and buy some more tape and re-apply them , good way to test on different boards
