I now use Flex Lock but when needed I use Loon head cement when I need a solvent based on for all synthetics.

I agree that simple is better. Marabou and chenille is hard to beat but tying small stuff can be hard with marabou until you are used to it. Calf and/or squirrel tail would be a good thing to have around when you want to tie in small tails and tie in wings.
