I sail all angles with 22" lines freeride craving powered and unpowered.
If its under 18 mph i dont even go out I'm blessed.
Flat water and rolling swell and lately some beach breaks in the baja.
Tresure island SF
Crissy Sf bay
3rd st Sf bay
The delta bay
And the last 4 months in the Baja
On a side note nobody has talked about placement of the line which can influence their actual length
I also use a waist harness with a sliding bar when it gets light I loosen it. That can add 4 to 5 inches.
Jason Voss is a pleasure to sail with at the delta he brings a competitive side out in you.
