The two puzzles are quite similar but are not totally equivalent.
HC2[F3 C4 E3 X9/2][F3] is the Curvyminx

I don't know your notation here, but I suspect we are saying the same thing. When I say "functionally equivalent" I am referring to a completely un-stickered puzzle, which means I am excluding differences like which pieces have unique orientations and which pieces have duplicates.
I believe this is a modification of the curvyminx but I thought it was unique when I made it!
It's interesting how people can often converge on the "same" idea coming from completely different starting points!
