Simple Stonefly pattern that has fooled trout for decades...Weighted underbody, dense chenille, and long squirmy rubber legs is all it takes for Pat's Rubberlegs to continue putting fish in the net. Fluorocarbon leader will help the plummet and get you in the zone.
some friends and I have been fishing Yellowstone Park in the fall for several years. A couple years ago while fishing for BIG browns moving upstream to spawn, the guide had us using his big rubberlegged stonefly nymphs. I stocked up on Pat's for the next year's trip and Slayed 'em! We've been fighting over them and fishing them ever since!
