My friend who is much better than me on ollies had similar problem when he switched board from camber to rocker. He had to play around for a while to find out where the pop-"zone" was. He described it as it was "later" in the press on the rocker compared to the camber. Now he is close to the hights he had before.
Good to know
The reverse camber board I have is very different from my previous regular camber board. It's one of those reverse camber boards with camber under the bindings. It also is a little longer and has magnatraction. I was able to get more air today, but I do think I need to ride it more and learn it's ways. It's irritating to get 5 inches of air when your use to feet.
I will say the board is way more stable than my previous one.
