We are tying tube flies with pre made polar bear brushes, and rhea, and tinsel.
They kick the shit out of any fly I've ever tied, or fished.
These are "April's". They weigh almost nothing, have a very low number of layers, and they perform exactly like you want them to in the water.
Lay down a base, tie in the polar bear brush, put the flash just in front, wind rhea three times.
Each fly takes five minutes or less.
