I guess I was wrong, Ross. It sounds like even bigger guys are recommending that if you have 2 kites, it should be a 16m and 9m.
I didn't think that was the case.
I just assumed only lighter riders could get away with that, especially in the overlap region of about 17 knots.

I guess I would look around for a 9m to hop on to from that 16m.
I don't want to sell you something that won't be useful (my 12m Ion).
