hey guys, i am going on a trip to florida in april and was going to rent a board, but i got the chance to buy a used board for only a little bit more than renting one for a few days would be. It is a channel islands rob machado signature series 6' 4'' by 18 7/8'' by 2 3/8''.(It also came with fins, traction pad, leash, and board bag) I was just wondering what size rider and what types of waves this board is for. I just couldn't find this board online (probably an older model) so any info on it would be greatly appreciated.
