When conditions warrant additional sinkers to get the fly down, I found some inexspensive beads to use instead of the bead head beads some of us use for tying our flies.

In the jewelry section at JoAnn Fabrics, they have magnetic beads that can be slid onto our leaders before tying on the fly. Allow the bead to slide down to the fly, cast and the bead stays with the fly. Better than using BB Split Shot. 36 for $1.99
