Saw several examples in the "Palomar Knot for Attaching Shock Cord to Snap Swivel" thread.
The simplest ones with the cleanest sides can potentially just fail under load by pulling out. The ones that add hooks outside the sheetmetal clasp plate will be stronger, but are also potentially snaggier, causing issues with deployment. The "coast" style that's just a 180 in the wire hooked around itself is non-snaggy, but can still fail by the wire unbending. A quick link is a good answer, but the 1/8 size is way too big and heavy for my rockets. I'm probably not going to build anything over about 12 ounces with motor and most of my builds will be in the 1-3 ounces range without motor.
I'm probably overthinking it, but as an engineer, I'm kind of a compulsive optimizer. What do y'all prefer for snap swivels for changing out different parachutes, streamers, etc. and keeping things neat and tidy while avoiding failure modes?

I also recommend the locking swivels. I've had good luck with normal swivels for a long time, then I had a couple of failures recently. I searched and bought some like these Ocean Cat brand on ebay. Rather than a package of generic snap swivels from Walmart for less than a dollar, these are more like $0.15 to $0.25 each, but the manufacturer does provide a pull capacity for each size. They're only a bit longer than the generic ones I was using from Walmart, but the wire is nearly twice the diameter. IIRC then ones I bought are rated at just over 50# capacity.
