OK, so I have had my backpack frame sitting around for a few week's and thought I would look into making a start on it. Its a vintage karrimor "kp" pack, not sure how accurate it is, but it was a good price. Now, I started looking into two crucial mods, the height and the bend (& height of bend) I found conflicting info on both of these... I even spoke to a armourer and he basically claimed that backpacks don't need a bend and that it is not accurate to have one!? I can't believe that as I've seen bends on almost every pack, so I can't understand why that was said? Anyway... is there a definitive height that is the way to go? I'm talking total height from the "shelf" to the top black caps. How high up do I do the bend and at what sort of angle? Thanks in advance, Kev Sent from my Nexus 5 using Tapatalk
