next revisit after riding all X sizes in various DW conditions.
As F-One recommends I like all sizes with the 145 Stab in all conditions the most. A friend that is 10kg heavier likes the 170 when the given size is at its lowend to squeeze out a tiny bit more lowend.
They really shine underpowered. 800 is my most used size, 700 when it gets good. 900 and 1000 when its flat.
Speedwise (SUP DW):
700: max speed 38km/h, fastest km 2:00min
800: max speed 35km/h, fastest km 2:10min
bare in mind that is in rather gutless baltic sea wind chop. Didn’t track enough runs with the 900 and 1000 yet to get solid data.
the sizing seems to be spot on. A fine line up for every kind of condition. Wouldn’t be surprised if they will add an 1100 next year
