Like a lot of flies weighted with lead eyes or beads, Clouser's have a jigging action. I suspected your crystal meth fly was a take off on a wooly bugger, most are.
Pink flies don't have to be weighted. I've often had trouble dragging the bottom with a weighted fly at Furry creek or on the beach near the oyster. Pinks will take a fly swung just under the surface at time. I got a kick out of doing this on the Squamish,with just ten feet of line off the rod tip. I could watch the fish rise up and take it. just like trout fishing or summer steelhead. I've caught them on poppers on the Vedder. They chase it across the river, sometimes 4 or 5 at a time, repeatedly snapping at it till one hooks up.
we all like to feel original but me I know most of my originals are take offs or adaptations on someone else's fly. I just have to add that little something that I hope will make it more effective. Cheers.
