Tins - attaching to line

[cow tamer]

I've understood that split rings should be used to attach tins to your line or leader. That tying direct is a no-no. And that even snaps take a beating with tins.
However, some tins like the ones by Point Jude Joe appear to have an embedded steel barrel at the hole or an embedded wire at the tip. What is the best form of attachment for these types, where wear doesn't seem as much of an issue? How do you attach the others where wear is an issue? Some split rings spread open when putting them on some of the thicker tins.

Virtually all of the old models of Point Jude tins had a hole in them. I have since made new molds and filled in the hole and made them with brass eyelets. This allows you to use a coastlock,breakaway,or duolock snap. Also you can tie direct to them.I believe there is a loop knot ,(rapalla knot?) ,that you can tie that gives a lot of motion to the lure. One of the SWE sharpies like Rob can chime in on that knot.The natural swimming motion designed into the Point Jude lures combined with the added action you get by attaching to the brass ring as opposed to a hole is unmatched and deadly.
