It caught a bass on its second cast, I've found flies can be used on standard tackle, at least if your ok for shorter casts on unweighted lures.I tried my hand at flies too. Never really got to try them out since I don’t know how to fly fish! That frog imitation sounds good
You can also easily add elk hair or feathers to the rear treble on any plug type lures, or to replace the feather trebles on inline spinners like roostertails
