Mike,

I think that leg color is so unimportant that I NEVER use rubber legs on bass flies.

I've found that it doesn't matter to the fish, so I just leave them off. Speeds up the tying a bit.

Only patterns I use them on now are foam spiders and few trout flies....on foam spiders I use either black legs with black bodies or black/white striped legs with grey bodies (only colors you need).

Confidence is the key, though. If you have confidence in matching colors, then use matching colors and vice versa.

Good Luck!

Buddy
