In late winter & early spring I spider rig flats and ledges on Ky. Lake. I use 8 12' or 14' poles spooled with 6# Trilene XL depending on how shallow I'm fishing. If I am fishing less than say 8' deep I use the longer poles to try to keep from spooking the fish before the bait gets to them. I use 1/8 to 3/32 oz jigs depending on what they want. I put a 1/4 to 1/2 oz sinker about 18" above the jig to keep it down. I use only tubes in the 2" to 1 1/2" lengths and tip them with minners if the fish want it that way. If I want to introduce some "flash" with no minner, I'll use a roadrunner style jig. The blade may not spin but it will flop around & cause some flash and some movement of the jig. I think the minner does the same thing.
I try to keep my speed down to .5 or slower when the water is cold. With my setup this speed puts my lines running at about a 15 degree angle. If the water is warming I may speed up a little. If I speed up I add weight to try and maintain that 15 degree angle on my line. If the water is real cold I creep!
Another thing I do sometimes, and this may sound strange but believe me it works, I gently rock the boat side to side a little every now and then. I have never told this before cause I thought folks would think I was full of... You know. I believe that this mimics a "jigging" motion, and causes the jigs to rise & fall, triggering strikes. I came across this idea one day when my partner got out of his seat to get a sandwitch and caused the boat to rock. I caught 4 fish while he was fumbling around in the boat! :D When he sat back down the fish quit. After awhile I started swaying side to side in my seat. He said "what in the h*ll are you do'n"? I told him "shut up & catch that fish." After he landed the fish I told him what I was doing and why. He said "you know, that makes since." "Let's ROCK! :D We limited out that day. It doesn't work all the time but then, nothing does.
This works well for me.
Hope this helps!
