So this will be my second attempt for climbing Mount Rainier via DC. Last time I climbed with Osprey Aether, it was nice, but it kept on hurting my hip and coming in the way of my neck. The overall frame was just too large. 60L was just good enough and I had ropes and a few other things hanging on the outside. Osprey was very uncomfortable on the Summit push, as it interfered with the harness and my head movement.

I am thinking about upgrading to an HMG. I see Halka and SouthWest (Rei). I am wondering if I should get those. They are kind of two pounds lighter.
They are both expensive at $400+ and I am thinking if its worth it.

Never done a CVT fluid change so far. First time planning to do it.
Should I just drain and fill, or should I flush?
I also see on the internet people are changing the strainer and the plug-in filter, should I change both?
