I'm just starting Power kiting, but would like to get into a bit of jumping, and possibly use the kite for a bit of land boarding after a I've progressed a bit. I weigh about 10 and a half stone.

Does anyone have any advice?

Thanks:

I've got a HQ Beamer 3.6 and it's great in the stronger winds, also enough grunt to pull along a landboard, even when not that windy.
Don't know about any others though certainly in that price bracket
Although the PKD Busters are well reviewed and are alright as long as you keep them moving.
