Heh, I guess I just gotta bite the bullet and learn to sinker start that Armstrong FG 34L board I bought for some vague desire to prone surf / dockstart (sub par for that purpose). Been riding an 85L rocket hardboard. It's nice to mow the lawn on a lighter wind day with the floaty board + I'm accustomed to higher volume boards to reduce possibility of recovery situations - I'm a weenie that never kitesurfed with a 3L plank and tangle of lines should the wind die.
Might just need something in between ~ 50-65L.
Of course, my board bag is too big as well for that armstrong board.
This thing:
wind.dakine.com/products/wing-travel-wagon?variant=41097772204215 weights 10kg on it's own before packing any gear.
Packability is perhaps less of a concern that peace of mind. For the most part, I'm coming around to - not bringing the board at all - if I go anywhere that can rent gear for me. The worrying about dings, the oversize baggage fees, overweight fees, lugging stuff through the airport shuttle, to the airport, and so on.
