I use snap swivels on all of my rods because I switch baits a lot. It may cost me a fish or two, but with the high speed movement of most bass lures I don't think it's a detriment. I use spooks, frogs, senkos, buzzbaits, spinnerbaits, jigs, and other bass lures. I think bass just aren't as picky as a fish like a walleye so you can get away with it. Well, I lost 2 big fish to swivel snaps breaking at the O-Ring. I don't know if they were northern, musky, or large bass that broke them. I don't need a swivel type, but that's just what I've always had. I've used many brands but they are usually expensive and usually rated for 35lbs breaking strength in the size I use. I bought a 20 pack (I believe) from Cabelas and it was like $17. Yikes. My friend said a swivels o-ring will get caught on a northern or muskies teeth will be popped open, even if it's not a big fish. That makes sense. I know one of them was big though because it bit my Ragetail Toad right at the boat and floated next to the boat until I realized he was hooked and he started to swim away. With one swish of his tail he was gone, blowing the O-Ring apart on my swivel snap. He appeared to be a 40"+ inch musky. That puts him roughly in the 12-20lbs. range I believe.
Well, I was looking for a substitute and I found Mustad KVD Fastach Clips. They come in 2 types, one with a swivel and one without. I've only tried the non-swivel version. The swivel version's o-ring is welded, which is nice, so far less chance of a fish breaking it. What's also nice is that you can find them at Walmart for cheap. They are $2.86 for a 12 pack. Oddly enough I haven't been able to find them on Cabelas or Bass Pros websites. Tackle Warehouse does sell both versions though. They appear to come in stainless and black. I assume the black is just stainless with a black coating.
Added benefit is that they seem to attract far less weeds then swivel snaps do. So that was a nice surprise.
My brother, my friend, and I all used them last weekend with great results. No lost fish and we caught about 8 northern in the 2lbs-5lbs range and over 80 bass, with one being 3.1lbs. Most of the bass were in the 1-2.5lbs. range. Didn't have one failure with the Fastach's. I'm sold. I've also used them on 3 previous trips and haven't had one failure. They are easy to swap out lures and unlike snaps you don't open and close them which can bend the metal and weaken it. They are cheap and don't break. If you need a quick change terminal tackle, this is what I'd get. We used the #3 size which is a 75lbs. breaking strength. I also have the #1's, but they are fairly small and hard to use with bigger hooks. We used the #3 with our wacky rigged Senkos and had no problems. Since they don't break, I think 1 pack would last you quite awhile.
Score: 10 out of 10.
I believe the Break Ratings is this:
#0 - 15lbs
#1 - 25lbs.
#2 - 50lbs.
#3 - 75lbs.
