When I do slow troll, I use a 3/8 oz. egg sinker 18-24" above a single minnow or jig hook. The rodholders I purchased from Grizzly Jig Co. What I do different than anyone I've ever seen is I still use a slip float with bobber stop to identify depth and as a strike indicator. Granted, the weight will sink the float, but you just reel up til the float is at the top of the water.
