saltgrassbear, where are you located in TX? I'm currently deployed to Iraq, but I'm stationed at Fort Hood (Killeen). I won't be back until Christmas, but if you're in the area, you're more than welcome to try out my Kifaru packs.
Kifaru makes a great pack, but what is your intended purpose? The only downside to their military line is that they are heavy, even empty (compared to civilian internal frame packs with the same capacity). If you need a bomb-proof pack, you won't find too many that compare. The suspension on their larger rucks (Pointman on up) is excellent. It just plain sucks carrying anything over 60lbs in my 'ol large ALICE for more than a 10K ruck march, but I can do over 100lbs much more comfortably in my EMR (no that's not my regular backpacking weight

). Balance is excellent, pack compression works great, and construction is bar none.
I'm currently using a Zulu over here in Iraq. It's my "travel ruck", I mostly fly rotary wing out to most of our unit locations, so my ruck gets more time thrown into and out of birds, vehicles, etc. It's been stepped on, compressed, pulled, dropped, kicked, etc...your light weight trail pack would not stand up to that kind of abuse. Many complain about Kifaru being overbuilt and over-weight; for the most part they are correct, that's why I ask "what's your intended purpose and requirements?". For me, weight is also a concern, but having something fail is not an option. I can compromise on the weight issue as the "overbuilt" part gives me what I need. Again, the military line of Kifaru packs are not for everyone, especially the extreme light-weight backpackers who are much more focused in some areas where I won't compromise. Different strokes, but each is a valid concern and you have to find out your own needs and balance them with what you're willing to pay for.
Now, the PALS/MOLLE webbing is great if you plan to use it, however it's a two-edged sword. First, you can "over-external-pouch" your pack, which can added a lot of extra weight and disrupt the balance. It does, however, give you a great platform to modularize your immediate need essentials (IFAK, bino's, etc.). Now, without any pouches, you're just carrying a lot of extra weight and if you do any major "off-trail" hiking, it can really get snagged on thick vegetation.
I know they are pretty expensive, but if you do any comparisons to Mystery Ranch, Arc'Teryx, Lowe (military versions, hard to find CONUS), Osprey, etc., you'll find they are not the only expensive packs on the market. For me, they work for both my military duty, recreation and even my own "bug-out" set up.
I have the EMR with a piggy-back Scout option
Second Scout for hunting
Zulu for my current deployment ruck
Pointman (haven't been able to use it much since it's sitting at home

)
E&E pack
I also have an Arc'Teryx Tango pack which is very similar to the MMR and even takes Kifaru pouches.
If you can part with the $$$, it's an investment you'll only regret if you don't get out an use them.
