I've been doing this board since Matt Biolos came out with the video 55 19 1/4 2 1/4. Being about the same weight as the average young pro surfer at the time, I made a round one for myself with these dimensions and rode it non stop for two years. With a slight concave and a slightly flatter deck this design went in absolutely every surf type you could imagine with a wave height limit of over head and a half. They have flow from the smooth drivey centre and lowish rocker, but can turn on a dime due to their lack of length and constant curve throughout. Surfed at a few inches below your own height they are the closest thing to not feeling a board underfoot. In tubes you see no pointed nose in front of you so you feel pretty much like the son of God himself.
