Oxygen is an enemy of rubber? Thought it was Ozone.
Yes, oxygen is corrosive. Ozone is a pure oxygen molecule I think and
very corrosive.
Silicone legs? I'm not familiar with them but seems like a good choice.
I'm sure you've seen them before; they go by the name Sili Legs among others. I'm partial to the black flecked pumpkin for hoppers and golden stone nymphs and I use the clear salt and pepper on some of my Steelhead bombers. Unfortunately it's not round, but I don't think the fish care. It is translucent to a degree so it can't replace rubber across the board, especially for patterns that need solid opaque colors ie., black, white, yellow, etc.
I was just going to tie a few using your suggestion of flash dubbing. How about root beer to match their brownish bodies?
Come to think of it I don't think I've had that flex floss rot, but it probably will/can.
Na, your right, that stuff is good to go. It's actually spandex, the material they put in girdles, socks, and things to make them stretchy. I also like to use it for ribbing and floss bodies. I use yellow for green drake ribbing and the red for Royal Wulffs. It's lighter, doesn't absorb water and will compress better than floss at the tie down. It also splits for use on really tiny flies.
