A lot of people compared these 2 kites BUT really the dynamics change related to kite sizing, wind and wave conditions.

So this is the scenario:
rider: 68 kg rider, 6 years experience kitesurfing, 1 year experience in waves
conditions: 27-33 knots, side on-shore wind, mushy waves, quad surfboard

First though is lithium 6m BUT WHAT I WORRY ABOUT IS whether side on-shore conditions are not good for lower aspect ratio kite that flies back in the window...meaning you dont get good upwind and drags you a lot downwind to the shore? am i thinking correctly? Is Lithium really bad on going upwind?

Is varial 6m a better option under this conditions? Varial flies further front in the window, it is a racing kite...really is it an option for wave riding compare to the Lithium which pivots more and helps when wave riding? A 6m Varial might be too "aggressive" for wave riding at 30 knots? The fact that varial has a forward turn will it help in these conditions...is it a plus?
