The build my own campaign has been accelerated and I'll be adding at least one new rear wheel to the garage.
Right now the plan is:
Rebuild the 36h Ultegra rear hub that the OP is on with a Velocity Deep V
Rebuild the 32h Tiagra rear hub with some other rim, possibly a DT 1.2/585 or a Deep V
Purchase a new rear. Components to be decided.
So, the question is: With my desire and this opportunity to try a few different rims, what would be your third choice for a clyde training rim?
(presuming deep V and 585 are already on the list)
Unless the spokes that "let go" pulled out of the rim, the problem isn't with the rims. The problem is with the wheel build and with the spokes. The spokes were probably not tight enough nor tensioned properly.
The other issue is that rims seldom have much to do with wheel strength. The rim only serves as a method to hold the spokes in place and as a convenient place to put the tire. The rim 'floats' on the spokes and the spokes are where nearly all the wheel strength lies. The rims and hubs that you have chosen will do a very adequate job for just about any wheel. Don't overlook the spokes...a common misconception. If you go with a DT Alpine spoke or a Wheelsmith DH13, you'll have a truly stronger wheel over what you are currently using.

Denting rims isn't a rim problem.

Bingo! Your dented rims resulted from a low tire pressure and, probably, from hitting stuff on the road without unweighting the wheels. The fact that the rear wheels were the ones that were dented suggest that you 'ride heavy' in the saddle rather than 'ride light' in the saddle.
When you ride heavy, you sit on the saddle like it's a chair. When you hit something, the wheels take the full impact. If you ride light, you hover over the saddle most of the time. When you hit something on the road, your legs take the impact and let the bike move up and down under you. It takes most of the stress off the wheels.
Finally, if you are riding on tires that are 35+mm wide, 85 psi is okay. But you since are riding on 28mm or narrower, that way, way too low.
