Bora 80 versus Bora 95 Backpacks?

Evaluating a new backpack primarily for hiking but also something I'll use
backcountry skiing. Bora 80 seems like plenty of room for most reasonable
scenarios, but I wonder about having the extra capacity of the 95 "just in
case." On the other hand, the 95 has a slightly higher center of gravity
because of its longer spine, and with anything in the day pack on top, I
expect I would feel that skiing. Any experience with these packs?
