RE: Which board should i choose carve 144 vs go 170
i sail my Go139 up to 5 bft, i weigh 90 Kilo and i can stand perfectly on it. I love that board nad it's got early planning, with my weight and a 7.6 i can gt into a plane in a light 4 bft. As the C144 and Go139 have comparable content i don't think it will be any different. Also, as you said, the range of the C144 is more interesting and because of it's width vs its length it will give you earlier plannning then the Go170.
Also you can sail it longer than the Go cuz it will give you more controle in the tacks and in jibes as it's a freeride board which has to act quickly, whereas i find the Go tends to hesitate in the jibes because of it's width.
Where in greece do u live, maybe that can help us help u choose?
