Tnx on answers
I have Futura 133 and for my weight (95kg) it is very good board, and I use it all the time usualy with my 7,5 sail. What I have doubts about is that on my summer vacation spot where i spend 3 weeks there are more light wind conditions and with F133+9,0 I could not plane. It was missing a bit to get planing.
So I am trying to get more info should I get only new 2nd board (wider) or I have to buy also bigger sail.
