You are obfuscating the argument. The argument isn't which is more effective. ( though I think at certain times/ conditions) spin fishing is more effective.
The discussion is why do fly fisherman think they are elite.
If fly fishing is more effective, is that not the definition of elite? If so your point is moot.
If fly fishing is not more effective, then special regulations, just like archery seasons, are befitting of the sport.
The game commission isn’t setting aside entire game lands for recurve bows only. On the contrary there are many areas around Phila that are weapon restrictive for safety concerns but restrictive none the less.
So why do you think that areas a designated fly fishing only? For a variety of reasons. 1) Fish caught with flies or artificial lures tend to be caught in the mouth vs swallowing a bait, thus allowing a greater percent of fish to be released alive. 2) introduction of non native, or invasive species, or parasites getting transplanted via infected minnows, non native minnows, crayfish, or noxious weed contaminated soils from worm cans. 3)Litter. Bait comes in cans, bottles, Styrofoam containers, plastic bags, and usually fished with bobbers and monofiliment. Yes I do see an occasional fly in a tree or lost indicator. But it is a fraction compared to the amount of balls of mono, Styrofoam containers, bobbers, plastic bags, power bait bottles, snelled hook bags, spinner packaging ad nauseum.
