I'm not an expert but i prefer the Drennan feeder (as shown)
2 of the 3 flights are weighted so it always lands the same way up, i use 8-10lb mainline with a hair rigged hook on about a 4" hook length. If you don't know how to load the feeder with ground bait do a search on google, you'll find many articles on the subject even a video or 2!
Remember, a loaded method feeder is a heavy old lump you need a bit of power, I use either a Korum twin tip or quiver 12" rod.
The setup is a bolt rig and will normally result in the fish hooking themselves, the swivel is only pushed in the bush so will easily come out if the feeder gets snagged up.
Good luck!!
