It was only after seeing Mod7Rem's pack did I commit to this build. He provided valuable feedback!!

I have an angled Swaro and Slik CF 613. I have used side pocket on other packs before and have no complaints...For my style I wanted a nimble pack which meant not too much "width". This system sucks up tight to the back and has built in padding so if you tip over backward you won't crunch your optics too bad.
