So...after all that I only read "I want a board that can do it all." So get a good all-around board.
Tell me if I'm wrong, but it sounds like your priorities are:
2. All mountain riding, w/speed
3. Progressing to bigger jumps
I ride and can highly recommend the Rome Mod Rocker. It might be a bit stiff for what you're looking for but I can press my Mod Rocker well enough. It is mostly a jump board but its made to take on anything in the park, plus it handles very well at speed.
