I was a fly fisherman until i was twelve then i opened my mind and evolved into a fish slaying maniac. If snagging was legal I would drag 10-0 treble hooks through every hole in the northwest! Ha Ha ha! Nothing is sweeter than watching my dad thrash the water on fish that won't hit a fly only to watch him look over as i land anouther big fat steelie......"do you want me to hook one for you dad?"
ahhh yes it is so sweet.....and to answer the original question...you can fish a fly on a float or cast it out on a three-way, troll it, tip it with a maggot, or trol it with leaded line. These techniques i use quite often with a lot of success, sometimes with better success than my pop. once in a great while I have to break out the Winston and pretend to be a little snobby. "yes Charles let's do some casting and later we can eat cheese and drink wine while we make fun of all the poor people." (just kidding)
I love the treble hook on a fly idea, sence i don't let any legal fish go until I have my limit Im not worried about releasing them. I quit fishing when my limit is reached because no matter what fish kissers say, the fight itself, reguardless of the unhooking process, kills millions of samonoids every year....But I guess thats sporting, or at least it's great fun for the guy who gets to kill tweny steelhead in a day while only tagging one. Remember going from a 5 techniques to 1 is not evolution, it is regression.
