Hi,

That red tin - green tin debate is really a good natured carryover from bamboo. Rodmakers don't want silicone around since it prevents varnish from sticking to the cane; this probably has nothing to do with fishing the rods later, hence the good natured part. Both work, as do many pastes for the reasons Jim states so well. For nymphing, the only problem is wearing off the wax if you've used waxed Unithread, as far as I'm concerned, unless you want it to sink even faster than bare polyester allows.

my 2 cents,
Kat
