Co-Pilot Lining question

[Frank II]

I'm thinking of getting a Co-Pilot to add to my TB collection. Only I can't decide between the Black/Steel ballistic nylon or the Steel Dyneema.

The dyneema version would be better for light travel except I'm concerned about durability. For anyone who has the Dyneema version, is it double lined--as in an inner and outer layer of dyneema--or is it just one layer like the packing cubes? (I'm not talking about the solar dyneema lining, just the areas where the inside is also steel.)

I held both versions of the Co-Pilot at the shop, and I own a UV Synapse.

There are two layers of Dyneema and they are as strong as as the Ballistic/Dyneema version albeit a tiny tiny bit lighter.

The very strong pipping and industrial strength finished seams to the pipping make the difference between my very floppy. squishable, expandable and packable Packing Cubes Backpacks and Shoulder Bags versus the Co-Pilot lightweight but rigid frame.

Why we finish the seams - TOM BIHN Blog: We make travel bags in Seattle, Washington

The only reference I can give is the Shop Bag, which can be squishable up to its piping that is why it is packable but only to the extend of the size of its very strong pockets and there is a technique to pack it into itself. (Thanks for the video Maverick!)
