Well, to start with golfman,,, try to keep it simple, cause well, it is'nt as complicated as a lot make it out to be. Time on the water, and by that I mean, fish, fish ,fish.You have to first figure out the best water to fish with the fly, because not all of the Vedder's flow is perfect for your fly presentation. And you can also keep your fly choices to a minimum. "Bright day, bright fly,,,,dark day, dark fly"....is a simple rule that you can start with. I only use 3 flies basically for the vedder,, I just change the colours according to the type of day it is. You can't go wrong with black, purples, oranges, and pinks.
I also don't believe you don't have to "dredge" the bottem with your fly for results. I love to swing the fly and I like the fly to occasionally "tick" the bottem ,,,NOT snag the bottem. At the end of the swing,let your fly "hang" in the water directly below you for a few seconds. I connected with one yesterday using this method and it quickly bolts you into reality real quick like.
Myself,I still seem to be one of the few that has not gotten into the two handed rods yet. I can't seem to step away from single hander, and I don't see a need for it personally yet(okies, well maybe the odd day on the Thompson when I have the wind blowing the fly into my face). You should stick to a sink tip for now,until the weather warms a bit and the fish will get a little more aggresive. Once you hook your first steelie on the fly, it will all come to(well, maybe not ALL at once). You will realize that you are doing things right and have been for awhile, it's just sometimes the steelies are not cooperating with you. I spend a lot time on the water and there are times when I wish I had a drift rod,,, but once those fish start cooperating,,,,alll is good. Yesterday they starting cooperating after 11 previous visits this year without a touch. So don't worry, they will come,and when you do, you'll be glad you stuck with it.
If you see a grey/silver Silverado with a yellow beacon on top,,, feel free to introduce yourself golfman. I'll be tossing with that single hander of mine the rest of the week on the Vedder and I can help you out if with a couple of things if you would like.
