I started tying up spoon harnesses last year after a few pointers from ebijack. did pretty well on them. As a rule when it got to worm season I would try to run 2-3 out of my spread with them and the balance in regular harnesses and scorpion spoons. I had no problem catching fish on them from 1.8-2.5 mph. I used 17# vicious last year, but broke off a couple hooks in the net, so I switched up to 20# seagar this year.
