once i had to inflate my ar3.5 using my mouth because i forgot my pump and eveyone else on the beach was on foils.
that's what i'd call a jellyfishing kite
power was staedy until the wings folded inside, then the kite did a little dancing in the powerzone and i did a little being dragged and screaming ... until it got back up and calm again.
when i tested the windtools booster 12 (16m flat)
i redefined my definition of jellyfishing.
this kite twisted and winded itself so much i was afraid to look up.
but the drag @ the bar was smooth and steady - almost felt like the kite did actively help to fly curves.
i've seen a blacktip 12.2 (2001) in about 25knots. far beyond top end (hangtime contest), the usual jellyfishing was reduced to a little wobbling (still scary).
at the top end, there's so much pressure on every inch of material, that there's hardly any jellyfishing possible.
