After a lot of research I bit the bullet and paid up for a quality lightweight external frame pack. I have taken it out three times now, 4 nights, about fifty miles so far. It is surely comfortable, the lumbar plate is a great feature and there is plenty of air space to keep my back cool. The shoulder straps are easily adjustable and there was no fatigue after 14 miles in 80+ degree heat. I was able to fit everything I needed for a weekend, including food and water. Sleeping bag inside, tent under the hood cinched down. My only complaint is the lack of exterior pockets. I wish it had one of two for a rain jacket, first aid kit, snack bars, etc. I will be adding a mesh pocket which should be a remedy. I plan on taking this to Philmont next year. I expect I will be right up to the 35 lb recommendation for max weight.
