Time for me to weigh in on this topic, I guess.


There are three types of bends used in overhead or safety pin style
spinnerbait wires.

Open or "R" bend.
Twisted loop.
Coiled loop.

I tend to prefer the R bend, since I would never even consider using a
snap or a wire leader on a spinnerbait. The purpose of the R bend is to
allow the knot to pivot all the way around when the line wraps around
behind the wires on a cast, rather than jamming into the twist. With
mono, the line usually gets badly nicked where it wedges between the
wires of a twisted loop. But with braided and fused superlines, it
doesn't seem to create a weak spot there at all.

The twisted loop allows a spinnerbait to be built on a lighter wire
frame, and allows it to be used with a snap (UGH!). But when tying
direct, if using mono or fluoro, it's hell on the line when the line
gets wrapped behind the wire, which is inevitable in using a
spinnerbait, because of the way they tumble in 'flight'. Like I said --
it doesn't matter as much with braids.

Finally, there's the coiled loop. In the early days of spinnerbaits,
they were pretty common, but they lost popularity, and these days, the
only place you encounter them anymore are on little specialty baits (EG,
the H&H spinner) and in spinnerbaits designed for musky fishing. The
latter use tells us that at least some anglers thing they are stronger.

Anyway, which you use is a matter of personal preference, unless the
thing directing you toward a closed loop is the desire to use a snap.
There is no advantage to using a snap on a spinnerbait. If you're
putting a spinnerbait into the places you should be putting it, the line
should be getting beat up pretty badly and you should be retying pretty
regularly anyway.
