Hard one to call this. Usually you'd say a high aspect kite such as a Rhino or the massively high-ar Flysurfer Speed. I was going to buy a 16.5 WildThing2 as it's much like the Rhino, but then had a 12m Da Vinci BAT on loan. Ok, it's got this mad 'low wind optimised' bat shape, but it's essentially quite a fat hybrid kite.
Been blown away by the bottom end though - was riding when the smallest other kite on the water was a15m. Hence I've gone for a 15m version of it, hoping it's going to be a light wind monster!
I think that kites like big Waroos and other bows are starting to change the conventional idea of a low wind kite. However, it seems that some hybrids/bows prefer low winds and some high - I've yet to hear of one that excels in both.
Still wouldn't mind a 19m FS Silverarrow though.
