I'm going to get festive here in a few and cook up some Elk for friends, so anything else will be later this week

BCS can not be modified to a BCS 2 sorry.

You an use extensions on extending above shoulders. I am 6'1 and a 24 inch frame is fine but for big loads above 60 a 26 inch is better. If you are 5'7" obviously a 24 may be sort of big in relation to branches. This is where the EVO has an advantage, you can trim the frame to 23 or 22.5 if you wish for non load hauling and be ok.

Gray is "technically" the same, but not soft hand. Different finishing method on the fabric. FWIW , I anticipate having a lighter gray that is a bit more quite at some point, but I am not 100 percent sure at the moment.

Coyote is the brown. There are photos in the shopping cart. It is almost exactly the same as the "Redwood Brown" tents. It is not the Tan .. which there are a few photos floating around of. Of topic, the Tan is not a bad pack fabric in it's own right, but just wasn't popular enough. It's not great for rock climbing / scree / talus , but not that much is that is lightweight.
