Me and my brother are doing ELK/Mule deer OTC hunt in CO this year for the first time. I have been using my old Alice pack for training. There is no way I am going to be able to carry more then 60# for any real distance. What I need is a pack that will let me carry that the most comfortable. I'm 5'7" 33 inch waist. The terrain is going to test my endurance I already know that coming from FL. Mountains of Afghanistan put a hurting on me 13 years ago and in a lot better physical condition. We will be doing day trips. I have been pointed to the Mystery Ranch Sphinx and the Alps outdoors commander and pack. But I'd like to hear from you guys that do this a lot more then anyone I know and can ask.
