Anybody that knows me knows my middle name is EXCESS ! If one is good a half a dozen has to be better. A couple of weeks ago I acquired a Buck Set Tru chuck and it only had a set of soft top jaws. I already had a set of rectangler
aluminum that I made several years ago and a couple of sets of steel pie jaws. Was able to score a set of aluminum pie jaws on the cheap also. I think the Buck chuck will be the dedicated soft jaw chuck .

Re: Soft jaw collection
Love the idea of pie jaws, especially for holding thin parts.
You might want to consider getting hard jaws for the set-tru, as it's really redundant in a soft-jaw chuck. Then get a regular 3-jaw for the soft jaws.
Having one dedicated is nice. I have one and it's easier to swap the chuck than the jaws.
If you need more soft jaws, I have some soft jaws for sale:

Re: Soft jaw collection
Yeah Steve: soft jaws on a Set Tru chuck is kinda like carrying coal to Newcastle !! Problem is the only set of Am Std. 1.5 bolt center top jaws I have extra have been modified with a counter bore on the ID. So I recon I need to keep my eyes open for a set on the cheap. Even if said set is a bit miss matched the Set Tru feature should correct that.

Re: Soft jaw collection
I have been using simple round ones. Quick and easy to make, cheap, disposable. They only have a longitudinal slot on the back, not keyed into the horizontal slot in the master jaw. Work in the inner hole for small work or the outer for big stuff.
The counterbore probably isn't even needed if you wanted to strip out even more complexity. Just use low profile capscrews.
This was a .200" thick piece of ABS with a really odd profile on the OD, the jaws were cut for a relief so that the contact is about in the middle, not at the face where any marring would be visible afterwards.

Re: Soft jaw collection
Now that I am a master of the art of soft jaws and one of their leading proponents, I must disagree about them being useless with a set-tru chuck. You still need them for delicate parts or parts that are just weird.

Re: Soft jaw collection
I'm with ccfl on the simple round aluminum soft jaws. They work as well as could be desired, and are easy to make from bar stock.
