Speeds on your trolling motor, get em BIG and they will almost stop the drift in the boat and you run the troller to maintain desired speed. I drag chains but have fished with a bunch of guys using socks, most of them have 2 sets. A pair medium size and a pair of the biggest they can get. Cabelas is the place to get em from what they say, been looking at em but chains have served me well as I dont fish deep water very often, rarely over 20 foot deep.
Good luck
