Hey, I'm fairly certain I want an KS Ultralight Omega 56l,but before ordering I'd like to double check if I chose the right upgrades.

First the pack list I plan to put inside of it from my last tour: https://lighterpack.com/r/i32c44 My base weight is at around 4.3kg, but including food for a whole week I'm at 11-12kg, and that is a bit too much for my back with an unframed pack. I'm 165cm and have some back problems on top, so I really want to do everything I can to not have any back problems while hiking.

Here are the options I'm going for: - EPX 200 X Ultra materia for the body of the pack, as it is the lightest, and the default cordura for the rest as these are areas which will see more abrasion, and the default nylon mesh for the back - trekking pole holders quick trekking pole holders, as I use trekking poles - dry-bag roll-top with closure system (seems to be the most convenient option?) - lumbar cushion for better back support

I think I have enough stuff (especially the large 233 Apex Quilt or my folded Thermarest) as back padding and don't need anything else?

Here's a screenshot of my PayPal order, hopefully I've put everything there which is needed: https://imgur.com/a/Fu1Ppdi
