As an experienced kiter / buggyer but novice (i.e never landboarded more than 20 yards without falling off) I would say that your best to learn when the kite is fairly powered up, to the extent that it has enough constant pull to lean against when boarding. It's hard to keep balance otherwise and you tend to end up snaking your way along the beach (from my limited experience). However don't go out so over powered that you do something silly with the kite and get dragged all over the place. Flying the kite without lookking etc is natural to me now for the time i've been doing it so I could get away with the stronger winds and small kite thing but if you dont feel comfy with that then don't risk it....
Im more than certain other people will either add to what im saying or tell me im wrong. If they tell me I'm wrong believe THEM not me cos I hardly have any experience with boarding.
P.S Welcome to the forum!!
