I rarely want to be on my only TT North Select 2010 40.5cm x 135 and i am 75kg
TT is only for when the wind blows offshore and i cannot ride the surfboard...and have to be a river rat
So if you are looking for system...lets say a 3 TT quiver...it would depend on your weight
People always refer first as the length...but i always consider first the width of a board then the rocker
If your body type needs the biggest TT for LW.....then 50x170
For moderate wind...then 45x145...........and high wind go for 40x135
Basically drop 5cm width between each board...and a bit more rocker as you drop down
Once again just a basic system...make sure you have the proper kite size that matches the board
