Very similar to the Sili-Leg Stone, but tied on a straight hook shank and with no knots in the legs, this fly catches a lot of fish, and should be in everyone’s box. It’s equally effective whether you’re trying to imitate a hellgrammite, a stonefly nymph, or just present a fly that looks generic and enticing. The wriggling, twitching rubber legs are impossible for fish to resist.
