149 would prob be too small for jumps, but depends on size of jumps. I would go with a 153 or so for what you seem to want. also consider capita green machine fk, ultrafear fk. nitro T1, and of course, the forum fav, the never summer EVO. (that is a small portion of a large list of boards to consider.
I'm around your stats, 6'0 140-150, 10.5 DC Boot (they run a little small, so im really a size 10 in most other boots)and i mostly ride a 152 Nitro Subzero for park, works perfect for me, and is just fine on jumps less than 40ft.
I tried a 148 capita stairmaster for a while, and found it to be too small for my liking. hopefully this helps.
