First the size. I'm kinda your size (5.10 150lb) and a 149 for 152 or all around is small. A 154-156 would be good. A 154 for more park, 155 for everything and 156 for more freeride. You have to be more specific on what you ride more. Freeriding, park, rails etc.
I don't know anything about K2 (nver ridden one) or a Jibpan. As for Capita, a all around good mountain board would be a Indoor FK(flat kick,more information on there site) or with FK, Green Machine, or even Stairmaster or Stairmaster Extreme. Also, look into Burton, they have some great all around boards. The Joystick, Custom, Custom V-Rocker, Easy Living Flying-V,Easy Living. Also, check out Nitro. Never ridden one but heard they have some great all around boards too.
