Thru-hiked the PCT in 2011 and met a pair of thru-hikers that loved the Talon 44. One swapped to the talon from a different ultra-light pack that came apart on him earlier in the trail. Both loved the Talon for their thru-hike (for as long as I hiked with them anyways). Know that you will need to be efficient in terms of space, but it will work if you're dedicated to a bit of minimalism. Hope this helps.
