Northshore sent me a sample of their GoSupreme pull-ons with my case of mega, and I have to say they're okay. ("okay" is going to be my highest rating for pull-ons, for various reasons) Waist elastic wasn't as over-the-top as I've seen in the past, while waist hold was good and leak guards were actually useful. (the leak guards on many pull-ups are a joke) The padding didn't come up very high at all in the front is my biggest issue. I don't know if that's what they want to do though, as they're not intended for capacity. But it does prevent them from being an effective side-sleeper option. They should work great for minor daytime IC though. With the changes to the waist elastic, they're the best fitting and most comfortable pull-up I've tried.
(padding in the back is slightly better, so they probably will work acceptably well for light overnight use if you're a back-sleeper)
If you're considering trying pull-ups, get some samples from NorthShore. They have a few different types and you might find something you like.
