I can give a few impressions on the Focus after about a three round test. I received the bag as a Father's Day gift and have had a chance to use it on three or four occasions. I only got the bag itself, not the 2.0L bladder which was sold separately. I've since then purchased a 1.5L Camelbak bladder and insulated tube (trust me, this is a must) to go with the Focus.
The build quality is REALLY good. Feels and looks like a well put together bag right out of the box. Reminds me of a high end hiking bag to be honest. When loaded with discs, water, or discs and water (see below) it sits very comfortably and is extremely lightweight. Shoulder straps are comfortable to wear around the course and the bag doesn't really trap heat against my back. I haven't really used the chest straps as they seem a little redundant for the weight of the bag, even with water. The backpack is pretty easy to get on/off, and I never felt like I was struggling with the bag or straps. I liked that I was able to wear it into the woods/rough to look for a disc without fighting the bag through brush like I do with my standard bag (Fade Crunch + Phenix quads). The 'stuff' pockets are placed well, hold wallet/keys/phone fairly well (they're a little undersized to get a pair of sunglasses in without worrying about crushing your specs). In fact, I use an app on my phone for scoring and I could get the phone in and out of the pocket without taking the backpack off. One thing I really liked was that after walking to my disc after an upshot, I could reach over my shoulder ala Barton/Bishop/Queen/Harper and pull out my putter for the putt without taking off the bag (as long as the putter is in the top slot on the bag). The bag doesn't stand upright, but easily leans against any tree/rock/bench without collapsing. I could get a Huklab towel to ride well in the bungee too. So... discs, water, towel, phone, keys all in a compact, lightweight package.
The ONLY downside to this bag so far is the capacity with the bladder. The UPD website mentions 4-8 disc capacity. The actual capacity (in my experience YMMV) is 5 discs w/ water, 7 discs without. I played a round with no bladder and carried a water bottle. Did not like. It was only a handful of holes into the round before I was wishing I had a bladder of cool water instead of a plastic water bottle that I had to set down constantly to shoot. You have to carry a bottle unless you're going the 'beener route and clipping something on the bag which might negate the balance and lightweight feel. I didn't have any issues with the disc capacity (7) for that round. The capacity issue is that the volume of space taken up by a bladder makes it nearly impossible to get more than one disc in the two lower slots and depending on the discs, the third slot as well. The top slot is high enough on the bag that the bulk of the bladder is below it so you can get two mids/putters in that slot without an issue. Notice that I used a 1.5L bladder and UPD sells a 2L bladder so I have to assume that the issue is only compounded with the larger bladder. Maybe it isn't as big a deal with a 1L bladder though. In fact, I used the 1.5L on a round but only about 2/3's full and was able to get discs in and out with just a little hassle. Once I'd gotten further into the round and drunk some of the water, it wasn't an issue at all. I blew through through water fairly quickly since I was spitting out a mouthful of warm water every time since I hadn't ponied up for an insulated tube yet. For the record, the discs I was using for my rounds were an Ion+Coyote in the top slot, Core+Leopord in slot two, Roadrunner+Surge in slot three, and River in the bottom slot. The bottom two slots are the real 'problem' areas and maybe with a little break-in the issue will take care of itself. However, given the build quality this could take some time.
In summary, this is a very well-built backpack and if I could figure out a way to disc down about one more disc, I think I'd use it even more. I like it for quick rounds on courses where I know going in what I'm gonna need. I wouldn't plan on using this for a tourney of any kind, however for a rec rounds on local courses, travel rounds when out of town to well-researched courses, Ace Races (or similar), or just taking a handful of discs out for some field work this is a great bag. I got several compliments for friends and complete strangers on each round that I've used it on. It's easy to tell that it's a unique design, good quality, and has a definite place on the course.
