Do the small noodles work ok? as far as big fish pulling them away? I mean the 2.5"ers? I've heard that they will pull them down but cant keep them down for long. I've read on here that the 4"ers work really well and I've seen several photographs of noodle rigs with the 2.5"ers. I've bought the 2.5"ers and was wondering how long will the fish keep em down? This is my first post and i'm new here any help will be greatlly appreciated. My rig is 24" pvc, 12" noodle, capped at both ends with eyebolt at one end. Second Question;;; How long does my inside weight need to be? I have some pieces of rebar- 3/8. Thanks in advance and god bless.
