I’ll be retiring in Oct, 2010. I plane on doing a thro hike the following spring. I am looking for the best pack for the hike. I have four packs now, all seem to have various fault’s . To small, not comfortable on long hikes, not set up very good. I have been looking at McHale packed for some time and believe I’m going to order one. Will I be better off ordering one designed to carry 50 to 60 lb. event though I usually carry 35-40 lb. for a 7 day trip.
