I use the ball bearing locking snap swivels. I have a standard barrel swivel on the end of my Carolina rig I have pre rigged plastics that I change out quickly. I get more swinging smoother side to side movement on my hardbaits too. I can tie knots plus the ease of changing baits.

You need to use quality bearing locking snap swivels.

What many do here is have pre rigged leaders (wire usually) attached to their lures for an easy change.  I do it myself with a dedicated rod and my dedicated lures for 1 species.  The snap/swivel is not on the lure, I don't care for that extra hardware.  The quality I see use ranges from the cheapest money can buy to more expensive BB/ duolock ones that I use.  To my memory I don't recall seeing one open, break or fail in any way, regardless of the quality being used.  I use BB (I'm a bit more anal about this than many here) as an aid in reducing line twist, the smaller seems to work better, my size is #2 40-50# depending on brand.  Too small for bigger fish but for 40-50" ones that hit at 30 mph, it's been the perfect set up for me.

With a failure rate that I see close to zero, if failure should occur I'd bet 99% of the time it's my user error.
