Greenroom said...I like big boards. I can ride them. Get heaps of waves. My last board was 6'3 X 22 X 2 3/4 thruster. A board like this where I surf gets me into anything before anyone else has even started to think about paddling in

Pfft. Go bigger.

Ignore the naysayers - I reckon the board would be fine for you. I surf a 6'10" with the same width and thickness as a one board quiver in similar waves and its perfect. I weigh 90 kgs.
Completely different outline, but similar philosophy if that makes sense.
Sorry I can't help you with the Futures question from experience (I use FCS) but I like upright fins in boards as I prefer the release they afford. The Eric Arakawa would be where I would start, but I haven't surfed either. Just chucking in my two bits of what I would do with that sort of board. I do have a couple of very similar outlines - a 6'0 twin fin using keels and 6'6" quad that uses large FCS Performers - so I don't feel completely ignorant, just a bit ignorant.
