In my annual pilgrimages to the great steelhead rivers of the pacific northwest; and in my dreams to fish more of the great atlantic salmon rivers of the world - I envision more suitable swing water than I could cover in a lifetime (though I would like to try). With every cast, mend and swim of my fly, I see more opportunity to refine and improve every aspect of what I am doing and have no doubt that I will never even come close to learning it all.
However, if one deploys other means to find satisfaction in their home waters more power to these crafty anglers I say. I hope I did not come across as anything other than one voice from the perspective of the dedicated swinger, just as some have effectively put nymphing and indicators, et. al. into perspective in other threads.
In fact I have a lot of respect for the capable drift fisherman, savvy plug puller, and spoon/spinner angler as they really have figured out a lot about fishing and catching. Not my choice to fish that way, but there is no wrong or right, just many rights to each his/her own and we are all fortunate to have the opportunities to explore and indulge in these pursuits.
Ed Link, seasoned 30 year veteran guide on the Salmon River Idaho and an acquaintance I am glad to have made recently might say... "A good guide needs to know all 5 disciplines of steelhead fishing to make a living. One day you need to use Skagit casts to work down a tight bank, and the next day you'll place a boat rod in the hands of a cigarstore Indian and row steady down the center aisle just like you're in church on Sunday, sideways into the seventh row, over and stop at the pretty lady and place the hotshot underneath her petticoat without her knowing it." It's his mastery of so many angles that impressed me the most. Besides, Ed's shore lunch is so legendary that even an off day is worth the boat ride and the stories are as good as any you'll hear in a lifetime of river bull. Somehow I am left thinking there was no bull in Ed's b/s, or at least not enough to matter. Ask him about the rocks that line the canyon near Shoup.
I never knew that elk steaks and slow roasted red onions with a dutch oven cobbler could be so good by the campfire. Tom, Keith, and the gang sure put on a mean dinner I won't soon forget!
Anyway my point is, it's all good and each technique requires it's own brand of study, discipline and mastery.
