Go into Greenlight and talk to them about a rocket fish style shortboard. Thruster or quad... or convertible. Swallow or battail are proven winners. Something in the 5'10 - 6'0 range for you would be pretty good, I'm thinking.
loving the trac pad on the funboard, zman. Is that to keep the can of beer from sliding around?
Flyer or speed demon aught to fill that gap. I have a copy of a CI red beauty that is hands down my favorite HPSB, a bit thicker and has an that early 90's feel. Mine is 6'4 x 20 but I've got 50 pounds on ya.
I'm only 15. No beer. It's just how it came and it's fun on bigger sets because I can really get this board moving.
