Welcome to the Forum.
If you don't really "crash" your kites. You might consider
an SUL instead of a UL. Many of the trickier SULs are
really ULs, they're just not advertised correctly in my opinion.
You might consider an Aura at 4 ounces for those (no wind)
days you spoke of. Or perhaps a ProDancer, larger, true SUL
but no real tricks except when flown by people much better than
The Silver Fox UL is a bit on the heavy side for what you want.
I have a WM UL and really like it, but it is not a no wind kite.
Something like a Benson Inner Space could also be considered,
although more expensive.
Fly before you buy whenever possible.
