Pack that fits in Refuge T-Zip?

Hi everybody!

I'm looking to get an alpacka refuge and am trying to gauge what size pack would fit in the T-Zip. I currently have a Mountain Hardwear PCT 55L that I use for backpacking and has a very rigid frame which does not allow packability. I also have a frameless 40L Palan'te Pack but I think that it's too small for any packrafting adventures.

After reading a bunch of posts on the sub, I know that the SWD Big Wild is the consensus best pack. I also know that bigger is better, but I am wondering if a 95L Big Wild would not pack down enough to fit in the Refuge. I also really like Southernlite Packs coming out of NZ, and this 55L pack from Virga Packing Company is also intriguing.

I am not married to the idea of getting a refuge and I am also considering the expedition, but I like how light the refuge is and it seems like I can take it further on my back than the expedition. I am more than open to suggestions on whether the Expedition would fit my case too.

TLDR; What is the best pack that fits in Refuge T-Zip or should I just go for an expedition instead?
