i started tying what i could then went too super hardcore cool realistic stuff now i just tye simple 2 or 3 material fleis that i can crank out 20-50 a hour so i can spend more time fishing and have madd amounts for me and my clients or friends too lose in trees, under rocks, fishes yaps etc........ BUT its all how u like too tye em dude! if a 40 minute nymph works better for u giver i think the casting rigging fishing method etc is WAY more crutial than the fly.. i dotn think have the best vision and in places were they get the hell fished out of them even a well presented fly cant be passed by.......
