I am just about to put an order in for a new sweet potato FST but I am still undecided on volume so thought I would seek some input from this forum. To give you some context I am 187cm (6'1"ish) and weigh in at about 83kg (183lb)...the board will be used in 1-3 foot Perth (Oz) metro waves and I would guestimate my ability as intermediate. I am steering towards the 5'8" but the guy in the shop is suggesting the 5'6". From a volume point of view they both seem about right but I am concerned about going to such a short board (this board is replacing a 6'0" fish). Any guidance on the volume or length would be appreciated.
