Todd,

Ah, a bait loop. What would a fly flinger know? Sorry. My initial reaction is that it's just like a tube fly - conceptually speaking.

Went salmon fishing last week. Used herring for bait. What a hassle! Fly fishing's so much simpler . . . and less mess to deal with. But not too suitable for finding chinook in the big C.

Sincerely,

Salmo g.
