I searched the archives for a discussion on this as I SWEAR there was one in the last year or so but I can't find it. Apologies if this is redundant.
So I've always tied mass produced spinners like Blue Fox right to my mainline. No swivel. As far as I know you should not "need" a swivel with such spinners. However when casting from boat for coho the other day I noticed my mainline was getting all twisted up!! It was twisted up so bad I had to cut of 20-30 feet and re-tie
I put a snap swivel on the mainline then snapped it to the spinner and problem solved.
However, I just DON'T like the way it looks. Big ugly swivel before my spinner. Looks like something my 8 year old nephew would rig up. I doubt the fish will notice if it decides to pursue this annoying flashy spinning object in the water...but I just don't like it.
I couldn't be bothered to tie this up in the boat but what I was thinking of doing next time is...bead on the mainline that will not go through top eyelet (so you can't reel the swivel in and possibly damage an eyelet(s)), then quality barrel swivel tied to mainline, then a leader say 3 feet or so, then just a small duo-lock at the end of the leader. Quick and easy to switch out spinners/spoons. However I would have to remove the existing split ring and swivel from my spoons (not a big deal), and clip directly to the hole in the spoon.
I also notice that many "locally made" spinners have a swivel added to the spinner, but blue fox etc does not.
How do ya'll rig yours up? Do you think adding a swivel will make the spinner spin less? (I doubt it).
