I have the 5'8" x 18 3/4" lost sub driver as my shortest paddle board. Great board, on the lower limit of my paddle in at 75kg. Have had it out in 1-6 foot. Most I've ever paid for a board and worth every cent. Was waiting to get a hand me down off a pro I know but he likes them too much. I'd take any board in the lost stable but would prefer pu construction over FireWire.
