Got two springers that way last year. Ran it off the same length dropper I had been using for kwikfish. As long as the current is working good enough to get a spin it will and does work. Really have to be patient, while on anchor though they can mess with it for quite awhile.
Last spring, down near the mouth of the Kalama, there was a boat fishing from one of the wing dams. They were using whole red label herring on a mooching rig. 5 foot leader, 30 inch dropper. They were the hot boat. They dropped out 5 times for 3 rods in about 4 hours. Landed all 5.
I tried it early this year below meldrum bar on anchor. Very slow day that day so I was really searching for something different. (this was before the river blew out). I put a cut plug herring on my boys rod. My fishing buddy that day said "hey, that boat over there has one on. As I was standing over my boys rod I heard that ever desernable creeeeeaakkk...!!! Looked down and the rod was folded. Picked it up and pulled the hammer down.......cracker!!!
Moral of story. Don't be afraid to try something different. Those fish see tons of kwiks, prawn, herring and so on. Sometimes a different presentation will attract more attention.
I can verify that. I've always believed in the change-up lure or bait, especially flyfishing.
I was in a hog line a few weeks back with guys using quickies and I tossed out a big, whacky
rainbow spinner with herring fillet wrapped on the treble. The clippy hit it on the way down, did'nt even have time to put it in the rod holder.
