MR nice frame, new bag options?

[300wby]

So I have a Marshall on a nice frame from around 2015. I picked up a new unused nice frame w/o a pack for a good price.

anyone know what bags can be interchanged with the nice frame? Looking for something smaller than the Marshall I currently have.

I emailed Mystery Ranch a couple years ago asking if their newer packs that go on the Gen 2 frame would fit the older NICE frame. They said yes. So any of their current line up should work. I used the Pintler bag this year, I like it. The Metcalf is a popular option.
