Seabreezers, I just got my tax return so its time for a new board!

I've been pouring through different threads and the Or mako seems to fit the bill.
but I am unsure on the right sized mako for my needs. I weigh about 80kg and am an experienced kiter, I ride mainly in small to medium wave locations, average winds are 15-20 knots. I have a light wind TT and a stonger wind TT so am looking for a board to fill the sweet spot in between. I am really only interested in riding waves, hard carving and boosting. I don?t really get into much freestyle stuff, just the occasional back/front loops, dark slides ect.

From the limited online research I have done I am leaning towards the mako 150. There is no possibilty of demos where I live and I don?t know anybody with a mako.

So the question is what is the right size for me, and is the mako the right board for my needs.

Thanks in advance for your input
