I am looking for recommendations for long distance semi-kiting trips in Alaska. Here is the situation:

Suppose that 60% of a 200-400 km mountain traverse is kitable, given common wind conditions and the terrain.
Wind speed will vary. There is enough technical terrain that everything needs to fit in a backpack, but it can be on a sled to pull when kiting.

I am looking for a single kite which is weight-efficient and can be flown in a variety of conditions.

One suggestion was a Blade 4.9 on handles and 50 meter lines.

Any other suggestions?

These may help some:

I think if you are going on a long trip through varied conditions, fixed bridled kites are out and depower becomes a necessity.

You may want to contact the folks at Conceptair. They are the ones who do the Greenland crossings. I know for sure they didn't have a one kite set-up before but now they have the " smartkite ", who knows. I would guess you could go with one larger Smartkite and a much smaller one for back-up + big winds. Something about going X country and depending on just one kite seems a bit risky to me ?
