Take a look at the Elemental Horizons Aquilo and Kalais. I have used both of them and they are the most comfortable packs I have ever used. The two packs share the same suspension system and weigh 35 and 32 oz respectively in medium. The Aquilo is the larger pack and works best with a bear canister. The Kalais is more compact and is good with gear like that you have listed. I used the Kalais on the JMT in 2013 and didn't feel that it was up to carrying the BV-500 I used; too small! I had to pack it carefully and even then it was a squeeze with my gear. I used the Aquilo on my 2014 JMT through and felt it handled the bear can and my gear quite well with its greater volume. The customer service at EH is great and you can customize either pack. Worth a look at any rate.
