Both. poppers are more durable. make no mistake, these fish and all their anadromous relatives can be very aggressive at times and not so others. salmon can be enticed most of the time. however just swinging like one would for steelhead is very unproductive. you need to think outside the box. there is no book on salmon in rivers that i know of, and that's gray and great. discovery of a tactic that works and refining your fly design and lines to suit is fun and rewarding. often the outlandish works for salmon. big bright stuff twitched on the swing or stripped rediculously fast works at times. sometimes not. i would love a sub forum on salmon as coho are likely my favorite fish to target with flies. and yes the two hander is appropriate much of the time. i would love to compare notes with folks as i trend to develop my craft in a fly fisherless vacum. i learn lots from gear anglers.
