The link you posted didn't work for me, but this does seem like a
good idea.


Hmmm....try this

I tried making whole nymphs from closed cell foam, with the
same idea: weight on the leader would take it down, buoyancy
in the fly would drift it naturally, a tad off the bottom.
But the flies I made were too buoyant. Wing cases only might
be just the ticket.

My foam nymph experiments eventually led to the Marshmallow Nymph,
which is one of the best fish-catching flies I make. Marshmallows are
made with open cell foam, which soaks up water like a sponge......but
it still retains a few air bubbles here and there, which does give the
nymph
a little residual buoyancy--which is similar in concept to what you're
trying
to do.


I've tried your Marshmallows, but I couldn't get the hang of tying them. I'm
not very accomplished at the vise ( at some vices, its another story...) I
should give them another try.
