Mike,

Here's a list of streamers htat I really like.

Big Streamers:
Woolhead Sculpin
Dahlberg Diver with rabbit strip tail
Strip Leech

Medium
Marabou Muddler

Meduim to Small Streamers
Deena
Woolly Bugger
California Leech
Rabbit Leech

All of the small patterns can be tied down to #12 without much of a problem, You may need a dubbing loop for the rabbit leech.
