no needed on a senko...no weight either. Hook, senko, rod and you WILL score fish.
Note Mike that while there will be some posts for other species such as saltwater posts on cod/haddock/stripers, this site is mostly dedicated to salmon fishing which is tough to get into for "minimum money". Drop me an email and I can direct you to better websites for beginners advice on bass fishing.
Make sure you check out the fishing rules, when bass spawn there's a time of month maybe May 15 to June 15 where only artifical bait is allowed don't quote me on the dates though.
