Ian I've got to back you up here I saw you many years ago in the broadwater on the goldie with the flysurfer and rail board. I was about to buy my first kite and I was interested in your gear as you were overtaking everyone else on the water, jumping big, and cutting harder upwind as well. Having said that I reckon tube kites and board designs have probably caught up a bit since then.
Greenleader & Gasman, I think maybe you're missing something. Big kites can be great for 2 reasons: you don't have to work them, and the bigger the kite the slower you come down. I love doing huge floaty jumps on the 21, stretching out to meet the water then relaxing again cos I'm just hovering a foot off the water for an extra few seconds. Sometimes it feels like if I don't stretch down and touch the water with my board, I'll just stay a foot off it for good. Sure there's less adrenaline, but things like a sunset 'soul session' big kites are pretty sweet.
