Dont hate me, I just couldnt help myself and had to try it. I asked this a few weeks ago if anyone has done it.. So now I have and it works perfectly. Some may call it sacrilegious I call it being inquisitive Only used 4 Grimlocks for Top and 3/4s of the way down between bag and frame to attach to the frame. The 4 side compression Straps and bottom compression straps are all the Kuiu Factory internal straps and the 2 that it comes with to put on the bottom of the 3200. They hook to the Duplex and then where the exsisting buckles are for the factory side compression straps. The bag disconnects very quickly from the Frame easily I have 10 points of attachment. Next up is to try the Kuiu Icon pro 7200 Bag on the frame. Should be similar setup. So if your curious if this works I can confirm it does. Next is a weight test see how well it holds up but by everything Ive tried with this so far its passing with flying colors.
