The only way to see if something is going to work is try it, that is how I learned to fish with an a just a bubble. Years ago they used to fish at the cheese hole with velvita cheese. and you had to reel up so far from the bottom. The person who figured that out did not know until he tried it. I am not a fly fisher, never could get those little buggers to hang in to the hook, but all bragging aside I have not set a hook in close to ten years, don't need to.
