Trying to decide between the McHale CMII or the SCMII. Which are you guys using for multiday backpack hunting?

This year I'll be using the pack I decide on for a 10 day sheep hunt in the Alaska Range(estimated load w/ animal 80-100lbs). This is going to be my first sheep hunt and I'm pretty sure I'll be hooked but I am not sure how many of these type hunts I will do in the future.

For sure I will do my typical 1-4 day alpine deer hunting trips (typical load w/ animal ~70lbs) here in SE Alaska. And I will also be using the pack for family backpacking type trips where I carry most of the load.

Just trying to buy the pack that I can use for all of my intended uses and not be too terribly under/oversized.
