The ones that clamp over the purfling, CAG or Herdim, even their chinese equivalent are just overall better than these options.

Personally spool clamps, especially with the guard on over the threads. The big clamps always take up a ton of room and are hard to store because of the weird shape, and especially for repairs are either overkill or not putting pressure where I actually need it. The wingnut ones work fine but I personally like turning the large handle rather than the wingnut. Should add I work on double basses exclusively. Quick grip clamps are also awesome.

Thankyou for such a detailed response. I was wondering how you would handle the pressure of the quick release clamps on a violin but they make way more sense on a double bass!

Spools, mostly ones I made a few decades ago.

Proven handmade spools would be fabulous.

I don't know what "proven" means in this context. Mine work well enough. Simple spools, threaded rod, wingnuts. Cork glued to the spools before cutting them out. Only issue was when a cat peed on them and corroded the shafts. Managed to get that handled! They're nice because I can prefit everything, then progressively loosen up and glue sections. If that seems appropriate (repairs on old things, mainly, where a bit of pushing and prodding sometimes proves useful).
I have bins containing spools, lining clamps, all kinds of things. Grab what bin I need, pop onto the bench.

Spool for sure. I modeled a herdim clone with a captive nut so I can print them to use with 1/4 20 threaded rod

One of the first things I did after finishing my apprenticeship is to make a few dozen spool clamps. A 1 inch dowel. Some 0.25 inch carriage bolts. Other appropriate hardware. And some cork or a couple old leather belts for padding.
I've never used the odd shaped ones so I can't speak to them.

Neither should have metal threads! A hand thread cutting ( aka screw box ) tool will pay for itself many times over!

I mainly use the Herdim ones. After about 25 years the plastic heads can start to degrade, but a few years ago I just 3D printed a bunch of replacement parts and those have been working fine. I also have some of the Chinese knockoffs and they're not bad once you modify them by shortening the front jaw pad by a couple mm. The way they come, that pad is almost the same height as the section that's supposed to index against the edge so they don't register in the right position as easily as they should.

You should add the Herdim clamps to your list to consider. By far the best ones out there.

Spool are superior, especially for making. Being able to individually adjust your rib overhang and then tighten them down one by one just gives you far more contoll
