Hi sweden,
Yes, the Gong greedy is a "fish" like shape: wide everywhere, with a longboard rocker (quite flat) but some in the nose.
You can see its dimensions here
www.gong-galaxy.com/magazine/pics/1-hour-4-boards/so that you can compare with your new board
What you experienced that for your weight, you had to put all your weight on the far end of the tail to turn it, due to the wide tail and low rocker. In your new board you can go for:
- narrower tail for ease of getting on the rail
- more tail rocker for tighter turns once on the rail
Both factors decreasing speed on slow waves.
I would advise a board that would be:
[1] wide for stability in the chop
[2] not thick, because you are light, ~120l would be nice, you want thin rails to be able to bury them. Also high volume boards are actually less stable in chop (cork effect)
[3] narrow tail, because you are light
[4] short length because your waves have a short period, longers boards will feel cumbersome. 8' to 8'6" ?
