I've had a Golite Gust for about 6 years, and have gotten many miles out of it. No big trips (> 2 weeks)or thru-hikes, but a few 1-2 week trips, and lots of overnights, day trips, rock climbing, and backcountry skiing. the bottom barely has any holes in it, and it is in great condition with many years left (hopefully).
I'd recommend inspecting critical seams, and carrying a needle and thread, and knowing how to use them beforehand. You could reinforce beforehand, and that would be as simple as tacking some fabric on behind the shoulder strap attachments, but that would just add weight....
