I've always been a big believer in buy it once, buy it right and hope to keep the board for 5+years, will the carbon fibre GT last significantly longer than the GS? if so, an estimate of how long they would comparably last would be perfect. -
No diff IMO.
Is the 1kg difference in weight and construction materials noticeable once in the water? on the surf and on flat water? -
No diff IMO.. Carrying and lifting on and off the car roof is noticable.. but not by much.
I am only an average surfer(surfed a 9'0 longboard for the last couple of years), will the difference in handling on waves effect me at all? -
No diff IMO.. unless the side fins that come only on the GT help.. but I ran my GT without the side fins.
Is the grip padding a factor, the GT appears to have the better grip? -
Noticable better deck pad on the GT.
In five or six years time, would there be much disparity in resale value?
No diff IMO.
It is unlikely I will ever feel inclined to wind surf, but you never know.
No biggie..
IMO.. If you can afford it.. buy the GT.. If you can't afford the GT the GS will be fine.. Awesome board..
