I actually am not scheduled to tie streamers until next month, so I haven’t used these 4x hooks yet, but I HAVE used drys, jigs, 1x, 2x and 3x all year. The perform like hooks that cast 2 and 3 times as much, Sharpness, stiffness and strength seem to match industry standards. I’ve got an order coming in Saturday for 600 parachute Adams in size 12-22, I’ve already tied 100 from my stock. I’ve never had a problem, the friends I give them to never complain and when I buy Togens brand hooks, I have money left to dress some flys with. Buy a few, tie with them, poke your finger, bend them, fish with them, catch with them and bring the trout to hand, with the savings buy your fishing buddy’s the first beer.
