Thanks!
RE: Suspender Attachment
I believe the folks over at Maxpedition fully expected that people might want to use something similar to H-Harnesses with the Devil Dog because there are two D-Ring attachment points on the top of the pack that standard clips can easily use. (I say they probably thought of it, because the spacing is perfect, and I don't know for sure because the darn thing lacked instructions)
To attach the suspenders to the front of the belt I just replaced the two standard webbing straps and clips with two one-inch webbing straps with side release buckles that I picked up from REI. At first I meant this only as a temporary fix, but I actually ended up liking the way it worked. As an added bonus, the buckles keep the Devil Dog's belt strap from being crushed vertically. (Note: I moved the belt's restrictor clips off to the side while hanging it up in the tree, and forgot to replace them when I took the shot... Oops)
Yes, the Katadyn's pouch is attached to the webbing and was in front of part of the Devil Dog in the original photo so the pack looked smaller than it actually is. Here's a picture the filter hanging below the pack to give you a better idea of the size of the pack itself. The pack is in fact pretty large. It's amazing what I have crammed in there. The filter only appears as large as it does as I have a carbon cartridge packed with it, and because both are wrapped in layers of foam for protection.
As I mentioned before, I don't like the handle, except that it made it easy to hang in the pine when taking these pictures. Another thing I was disappointed in was how much space is lost internally when both bottle holders are full. You definitely want to pack with bottles in their place instead of trying to cram them in last.
