Thank you so much, Ola!!!!!!!!!!!! I'm very appreciate you found time to answer my question
a few more:
1. Would it be good to get convertible Quad (to one fin board) or a simple Quad? Which one to choose?
2. Also if I choose 76 Quad would it be good for light winds? I don't sink with my 99 L freestyle board at all and a sail 7,5 if there is no wind or having very light wind. Will I sink with 5,3 with the same conditions on 76 Quad or now? 76 looks great but ... I'm a little bit afraid for this size ... BUT I trust you 100%
so, please, a few more words for a size choice.
