Parker sounds like a few guys out there have found out how much fun a dog on a fly can be. If your snagging your flys on the bottom then try putting the smallest corky you can find on to try and help float your fly a little. If your tying your own flies then just use less weight or go down a size in the hook. I don't use very big flies for chum, size 4 or 6. I use a four foot to six foot tippet, 8 to 10 pound. I've caught fish both on the retrive and on a steelhead swing, mostly it depends on the type of water your fishing, personally I like to swing the fly wait at the bottom of the swing for a few seconds then do a few short slow strips. Mend the line when you need, the more water you cover. Anyway hopeall thos info helps you, I spent a few years finding this stuff out myself, I wish that I could have asked somebody questions. Good luck Fiveweight.
