This is a new twist on an old favorite.
The old rubber legged stonefly nymph has been one of the staples for ages when fishing freestone streams and rivers in the Intermountain West and the Northern Rockies with stonefly populations. So why change a good thing? The design of JARS is intended to accomplish several things ? improved profile, more action, better texture, and a shorter hook shank to give the fish less leverage during the landing process.
