It can be a real challenge to make a slim, tiny nymph heavy enough to sink down to where the big trout hang out. Hareline Tungsten Thread is just the ticket. More accurately called super-fine wire, this material provides weight without bulk, so your Blue-Winged Olive nymphs and midge pupa can be as slender as the real ones trout eat every day. It's flexible enough to tie knots easily. Adds weight without bulk to larger flies, too. Available in 2 sizes - Fine and Extra Fine.
