I have a cab lab rat 150cmX36 or 38 for 'rough and higher wind conditions'..I know it's old school but i find it's a great board for hard chop and cross swells. Being the only kiter it's hard to get ideas if I should get rid of it and upgrade. Am roughly 170lbs. and ride mostly 12mtr. on 12-18kts and if lite 8-12 i ride the switch 144 and a cab 14mtr.
I try to do speed runs on it and logic tells me the longer the board the lesser it would pearl in case a swell comes on to the path. Any ideas in size for the next board for the lab rat in size

right now looking at mags i think the ideal would be 130-135 x 38-43 but am just guessing
