I don't know the heights of the drops you listed, can you list their heights?
I do know that Mania ran the 18' entrance Falls on Valecito a couple of years ago.
There is a cool shot on the Aire page of Charlie Brown and Brad Merritt running a drop on Mill Creek in Ansted, West Virginia. Charlie Brown has run a shredder down a lot of stuff that will make anybody pucker up a bit.
I have also seen a poster of a couple of guys r2ing a yellow boat off a big waterfall (Kodak or Nikon poster I think), but I don't know how big it was, I would guess 30'+.
There is also video of a couple guys in Norway running a 30'+ drop in a creature craft.:
