Hi Smiles,
How big are you anyway? I am 120kg at the moment and was 129kgs about 3-4 months ago.
I currently own a Mistral Screamer 128ltr board and thats it. It works well for me and just floats me in next to no wind. I wasnt able to uphaul it until I got back to 120kg.
I did have prior to this board a 161ltr board and that was great to learn on, very floaty but as you get better those big floaty boards are just a pain in the arse.
If you can sail on a big learner board I would suggest getting something around 130ltr, there are plenty of boards in that range , like the SX Large I think is 133ltr etc (although I am refering to new).
It all depends on what stage your at I guess, I can plane in foot straps & harness, lite wind gybe, tack, water start. Hopefully it gives you an idea coming from another big guy.
I was out this arvo in around 14-15knts and was fully powerup on my 128ltr and 8.8mtr sail.
