Has anybody surfed a Surftech Stretch Quad. Looking to buy one and trying to get some feedback. If you surfed one, what fin set-up did you have and does this board surf the rear foot as well as they say? Looks like the stick has volume, but I am trying to get feedback on how much you way and what size you are riding it? it is tricky to buy because in surftech they jump from 5'11" all the way up to 6'5". "word?"
