I like the plastic tee-beads in front of the swivel and use em all the time, especially in Elk & Beaver when they get swampy. They fit right over the eye of the swivel & even keep chains clean.
Clear, pink, chartreuse, blue or green.
I could see twist being an issue mooching, just maybe, but with the 20' behind a rigger-clip? I can't see that being a real problem. That 20' might be more of a problem if it was stretched-out & dead, but twist?
And, technically, spoons ought not pulled so fast as to be spinning, just wobbling... like dodgers. When I buy a new supply of swivels, I put the on a safety pin dunk them in WD40, pull them out roll the swivels around to ensure interior penetration, set them on a paper towel for the night & put the bunch in my vest pocket.
I've only had twist problems with spinning reels using stiff lines or with flourocarbon as a mainline. Or when cast & retrieving those PowerBait squids. man those things go all over the place using a jerk-retrieve even when only nose-hooked.
cheers!
