Important wing size tip
I think this is something that is not talked about near often enough. People are always talking about bigger wings for light wind days and about how much they weigh, but they forget the most important thing when buying a new bigger wing, their length.
I see it quite often on this sub and at my local lake. People think "the bigger the better", but this is far from the truth. There is an upper limit of what you can ride and it completely depends on your length. The reason for this is that if you would take out an 8m wing while being 1.75m, you will have major issues getting on foil on the very light wind days due to the wing tips. You cant properly pump the wing so the extra area of the wing is working against you.
I myself am 1.76m and the biggest I can realistically ride is a 6.5m wing (maybe 7 with the f-one cwc but I havent tried them). Anything above that you cant efficiently pump and youre better off getting a smaller wing.
Its better to get a smaller wing and work on your pumping technique than to get a bigger wing and hope it will lift you.
For reference, Im 1.76m, 65kg and I can get up on foil comfortably in 12 knots with a 4.5m wing and a 1000cm foil.
TLDR; Dont buy too big of a wing for your length.
