@thedoor, both feet deep in the straps most of the time for me unless swell riding and looking to do a transition. Been working on riding switch in the straps and lots of body twist, shorter boom sails help!
Also agree with earlier posts about using a wave (even just a small one) to initiate the jump. In fact it's more just a target to aim for as you can jump high off completely flat water but must be a hangover from fin sailing to line up a little ramp and pop off it...
Landing still a work in progress, fairly big impacts sometimes but nothing like flat landing fin jump lol.
