Hohwaiian,
By thinner backer rod, I assume you mean smaller than 3/8". I usually use 3/8 with a sequin and yarn pulled through the bugger, but I have used the thinner stuff. I used to cut the thinner rod a little longer than an inch(1.5") with the yarn pulled through off center and a little longer when the yarn sticks out. I thread a sequin, then the thinner rod with the yarn offset up top or away from the hook. It has a little different look and I have caught a few fish on this. I have seen guys run a bead, inch and half of the thin stuff and yarn tied above the rag onto the line.
