The frame in the last few pictures, with the metal hip belt things looks like some kinda bondage device. Is that shape wearer specific? Maybe if you added spikes you could market it to the oldest profession industry. <img src="/forums/images/graemlins/grin.gif" alt="" /> Also, I would think that an external frame setup would be capable of carrying more weight in a more comfortable fashion. My first pack was a frame setup and although you can lash several items to it for versitility, I'll stick with the internal I now use. I did once consider building a frame out of wood stressed with rods etc. Not sure how it would hold up but would be a cool retro/antique look. I believe that if constucted correctly it could be as lightweight as most metal frames. <img src="/forums/images/graemlins/smirk.gif" alt="" />
