Hi
I haven't sailed the 85L Quatro Freewave but i have used the 75L a few times. All i can say is that you will not be disappointed at all. Iv used it at lano, crazy waves and dutchies and its always handled it fine. Its a super easy board to use and it makes sailing FUN, planes easy, turns great (too good at times

), floats well, etc. Go see Alberto at Windshack as he may have the 06 75L demo board you can use. For a Perth based board i would look no further.
With the Goya i haven't used them but iv used the 05 78L FW and that was great too, i personally prefer the Quatro but as its kinda more wave based, go and have a look at them.
Regarding the sails, may i suggest Hot Sails Maui Superfreak. It is a different sail and i think you will either love it or hate it. I love them (don't own any though) and they have a HUGE top end and are very controllable. Iv used a 5.0 when i should be on a 4.2 yet i can get planing really early with the 5.0 too. Also they are just about indestructible, just food for thought .
