Give it some more time. On the first couple of runs with my hybrid camber I thought I made an awful purchase decision. But I stuck with it since I was 5 bills deep into it and figured out what I needed to do and not do compared to what I was used to doing. Basically I was over-riding it because I was used to an old, heavy, stiff cambered board.
You might find you prefer camber. If that's the case, just get a cambered board. But give the new profile some time, you might find you like it.
The suggestion of getting a lesson is good; there may be a technique issue a professional can help you fix.
Really good advice...and good to know that experienced boarders have a learning curve too. Believe it or not, I am excited to give it another try...or 4 or 5 :-).
