I have described in Luderick 101 - Rigging Up, the gear required to catch luderick and illustrated a simple way to rig a float. In that article I also described the types of bait required. In an article yet to be written I will attempt to describe how to cast a centrepin. In the meantime you may want to have a look at this link or this one

 This article will describe line maintenance, knowing when to strike,  and how to go about it.

Possibly the most common caged centrepin in general use is the J. W Young Rapidex, a highly regarded reel from a highly regarded manufacturer. What isn't commonly known, is that Grice & Young marketed several caged reels, most were fly reels, but also at least one centrepin.
