I mark the line with hi-vis thread , the same stuff you use for slip float rigs. Thats how I set the baits depth or height off bottom, same as a slip float rig minus the float. The drag on the reel is set very loose, but not to loose that the bait can take line. Last season I saw small okuma baitrunner spinning reels being used & they worked great. No need to adjust the drag upon hooking a fish. The okuma`s in that small size cost about 40 bucks.
