Okay, I have 3 packrafting trips under my belt with the Unaweep now (two overnighters and one 5-day trip), and feel somewhat qualified to make some observations. Total pack weights ranged from 30# (overnighters) to 40# (5-days).
First off, it is really a superb platform for hauling gear on tough trips. The suspension is really excellent. Extremely comfortable, and supports the loads that packrafting in Alaska requires. There is a significant amount of adjustability for various torso sizes by adding frame extensions and letting the packbag ride up and down on the frame. The shoulder yoke also has a wide range of adjustability in terms of raising and lowering it independent of the height of the hipbelt. All these adjustments can be a bit confusing at first and it takes a while to dial the pack in. Longer than any other I have owned, I’d venture, but the end result is lovely. For reference, I’m 5’10” and 185 pounds with a 33″ waist and a 22″ torso. I run the pack with a single frame extension (26″ frame) and have the hip belt in the raised position (the lower strap grommet) and run the shoulder yoke fairly high. The load lifter straps do a perfect job the whole pack drapes nicely across my back with no pressure points and supreme control. The fact that the pack ‘hangs’ below the hip belt means you can bend over at the waist and the pack does not restrict your ability to lean forward as the bottom of the pack can cantilever out. If you spend any time crawling through heavy brush, you will really appreciate this unique feature. The hipbelt is nothing extra special in terms of materials or shape sophistication, but is is extremely comfortable and suits the performance of the pack perfectly. This may be the first pack where I wouldn’t change a thing on the hipbelt (other than putting an ITW GT Cobra buckle on, as David C did). I did add a GG belt pocket though. I don’t have to reef the crap out of the hipbelt straps to keep the bigger loads from creeping down, and the weight transfer is really excellent. My pack with VX21 fabric and the standard Talon (the rear pocket) weighs 3.6# (1,650g) with Aquaseal seam sealing, the ITW buckle, GG hipbelt pocket, and some minor tweaks to straps and buckles.
Here are some of my mods to make it more packraft friendly:
I added a sleeve to the back of the Talon pocket for my paddle. The top of the sleeve is open and there is a 3/4″ webbing strap with 2 extra loops sewn on so that the shaft portion of the paddle is held securely.



I felt the standard position of the Talon back pocket was quite a bit too high, so I added a 1″ strap daisy chain to the “load shelf” and used a pair of releasable triglides to give me a few positions to play with for the bottom attachment point:

This way the Talon dropped about 5 inches and the tops of the paddles do not extend above the top of the pack much, which is key to negotiating low branches and busting through alders:

The lower compression strap interfered with the bottle pockets with the Talon so low, so I eliminated the lower buckle on the Talon and used that bottom strap to cinch the toll top down:

I added a small length of webbing to the middle compression strap to capture the lower strap so it would stay in place when I released the roll top:

As I mentioned elsewhere I moved the attachment point for the load lifters to a spot directly at the top of the frame so that the packbag wouldn’t get pulled into the back of my head. I personally feel Paradox should implement this simple design change immediately.

I felt the chest strap attachment buckles on the shoulder straps moved around too much (they are 1″ buckles on 3/4″ webbing for some reason) so I stitched the strap to the shoulder padding in a few places to make a daisy chain. This also allows me to attach my camera bag to the shoulder strap in a way it doesn’t creep down.

If you want an idea of the sorts of paces I have put this pack through, I will refer you to 3 short videos of the trips I have done with it. You will have to follow the links as the video players are sort of fake:
