If your having speed issues think about installing a Trol-a-matic trolling plate on your big motor. I have a 115 hp Opti on my boat and can troll down around 1.2 on a calm day at idle speed with no control issues. They are about $110 at Cabela's.
You want some good jugs get "Jug's by Burt" the best I have ever used. I do most of my catfishing down in Ok. You can keep the channel all we try to catch are the blues and throw the rest back.
Anyone fishing docks or between docks. This time last year I put my little neice and nephew on some good fish between docks in about 3-10 fow using green pumpkin finesse worms.
