Which Futura Size for me?

[Fran7802]

Hi Guys, i live in Portugal, close to windsurfpoint in Lagos, Meia Praia. I have recently been windsurfing or shall i say started and now i´m hooked!!! SO first of all i´m 6ft5 and weigh round 103kg. I´m quite athletic, but tall. I went down to my local windsurf store and the guy introduced me to a 2010 Futura 141L. I haven´t been for a test ride yet, but he assures me that this is the board for me. He reckons it will take my weight.

So my skill level is beginner, the last board i´ve been riding was a 175 High Fly mambo, it was ok, it did feel a little rocky, but not to bad, also i´m riding on a lake and the wind is not always very good, sails ive been using the 7m most of the time, i enjoy the power. Previous sails size´s 4.9, 5.5 ,6 and 7. i have not learnt foot straps yet or harness. Most wind i´ve been out in was about 18 + 22 knts, with 7m sail and i was ok, but only short rides in the lake.

So my questions is would this be a good board for me to start with, also is it a sinker, well with my weight??? or would it be quite stable and boyant because of the design. This is what i was recommended getting:
Starboard Futura Technora 141 2010
Severne NXC 6.5 2010
Severne White Line 460 2010
Aeron MCT 26 175

I really just want to buy the right equipment to progress now.

Thanx Guys
