Kevin, that one looks awesome. In the picture, do you have one of the supports inserted into the backpack? If it is, what pack is that?
As for interest, I am! But it is probably a little out of our league to give input on the design/manufacture. I'll just sit back and enjoy the finished product :)
OK, well it looks like it would be great for my winter pack. My summer gear is too light to require a frame, but I use a Arctic Drypack for winter and need the rigid support for the loads (15-18 lbs of gear plus fuel and food - adds up quickly). Being able to integrate it into existing packs would be great, but if you offered the cuben version at under 10oz, I'd be willing to buy the whole package.
As for the weight, if GG has one at 3.4 oz, surely the carbon version can be lighter, unless of course the GG version is not rigid enough and additional material is req'd to create the stiffness.
One more question, is there some flex to the hip wings? Are they required to transfer the weight? Just asking because I thought some people just used carbon shafts inserted into a CCF pad as a frame...however, I have not tried either so I have no idea if it works well.
Did I mention that looks awesome?!
