Hey Dan, I'm sure there are plenty of kites out there that would suit you, however as already said, the North Rebel is a wicked kite. Its responsive, turns fast, easy relaunch in the surf, and most of all has plenty of grunt, especially through turns. The Rebel does however lack in its un-hooked downwind drifting ability. If your doing more un-hooked stuff give the Evo a crack. It is really stable un hooks and drifts well but isn't quite as quick as the Rebel.
Another option is the BWS noise kite. It is one of the best kites on the market for its downwind drift ability, really good un-hooked and surprisingly good as a freestyle kite too! However it does lack a little in turning speed. Definitely better in an 8m than a 10. Also keep in mind that an 8m noise has similar power to most 10m kites!
Good Luck Mate
