Go try a seat harness
You probably wont like it at first
You maybe even hate it
The piont of attactment is so much lower
Pulls form the hips and butt,not from the waist or lower chest [if it rides up]
Takes a bit of getting used too
But if you stick with it,you may never go back to a waist harness
Be sure to tighten as much as possible
I have never had wedgie or crushed family jewels from one

as I have read sometimes
Pros, can jump higher,due to to lower POA [basic phyisics]
better for getting upwind,
never rides up,no need to be constantly pulling it back down
never twists around your body,
can kite all day no sore back
more comfortable,better for a long session
Cons,Not as good for body dragging,maybe
Does not twist around your hips so not as good for going toeside,
Not as COOL as a waist harness
Feels a bit like a nappy
