Dean – I went through a lot of the same thought process. I ended up buying a McHale Chasm but after a few years ended up buying an LBP36 which has become my primary pack. The Chasm felt great and could carry a bear canister horizontally, but it also weighted almost 4.5lbs and had far more volume than I needed for even week long trips. The LBP36 has more than enough volume for me and I have about the same 12-15lb base weight. The LBP36 is more compact and easier to carry in brush and scrambling, it weights just over 3lb without a top pocket or kangaroo pocket. I also don’t use a hydration system backpacking and the McHale side pockets are the best ones I’ve ever had for carrying water bottles. I did a full spectra back panel on my LBP36 and it really adds to durability of a high abrasion area.
