I hunted hard with my tz5000 this year, maybe not as hard as I'd like , but hard enough to break the sternum strap, and some of the zippers failed on me. It rode comfortably just like it had all summer when I was training with it. I think I didn't utilize all the space in the pack by keeping everything in separate pullouts, so packing 4-5 days worth of food was challenging, but doable. Packing out a deer would've been interesting but could've been a by product if me over packing. Overall though I feel like I got my money's worth out of the pack, I can only reasonably hunt with two weeks every year and I bought it used at a really good price...I'm trying to decide what I should spend my hard earned money on next though and I can't justify spending 500 dollars on a top of the line pack yet. What are some reasons for and against upgrading? I ask because I feel like having a non-biased opinion is helpful since I am historically cheap and hate spending lots of money, but I at least recognize this.
