If you enjoy fishing choppy runs in the colder early hours the microskagit-streamer approach is worth exploring. I started out with a poor man's skagit made from a line off of ebay years ago for $15-20 I think. I've since picked up an OPST/Lazar line setup and a Rio
Skagit Trout Max. They are phenomenal heads however I find I keep going back to my homebrewed integrated line. I would say the mono-loop-tapered-head setup is optimized for longer distances than I usually am fishing. Even on bigger rivers I tend to break the water down into small sections and work those with shorter casts whenever possible. The pvc integrated running line may not shoot well but its so much nicer to handle, especially in the cold.
I do carry a spare reel with a traditional floater for dries, wets, nymphs, strip-retrieving streamers all that good stuff. The microskagit is a dedicated setup for the right conditions, but I tend to look for those conditions more and more and as a result I use it a ton.
Last month I made this 6 min video trying to illustrate for some new-to-spey friends what I mean when I say I was 'swinging streamers with a tip'. As Ard and others have mentioned it's a challenge to communicate some of this stuff in text so after some ridiculously long emails I thought why not take a recent session on the home river and add some captions.
