Fantastic, but will make you reevaluate your 34A setup
The way I adjusted my LBV, the bottom 34A "chest strap" sits slightly under my pants belt and the top strap slightly above it, I'd say that's square "on the hips". I see people wearing it higher than this in promo material but not lower. When you have M4 mags in the internal cummerbund the outer ones sit exactly at the 3 and 9 positions, which is notably different from the chest rig config. Since mags are more easily reachable, I abandoned spud pouches in the "center". If you put spuds in the rearmost portion (at the 3 and 9) they are still very accessible. This led to me reversing my setup with two JSTAs center and spuds on the outsides. Keep on mind if you wear it on your hips, anything that drops below the panels will slap your thighs, as well as 30rd mags in the middle elastic slots. Abandon any ideas of danglers. You should absolutely fill the "gap" between the buttpack and 34A panels, it's a very large wasted space otherwise. Tall GPs are perfect here. Once you have it set up it carries weight so well, the buttpack stays extremely tight to the body with almost no "bounce". The straps are perfectly adequate, no complaints. Simple X shape with the ladderlock works surprisingly well for dialing out play. I question why exactly spiritus put a molle field on the back of the buttpack, I personally can't think of any application for fixed mounting it, but it gives you more options and it's unnoticeable against your lower back. You can copy the mk3 fanny sack and use the two bottom drainholes as shock cord ports for carrying a poncho/whatever externally. You can also wrap a fanny pouch over the outside of the buttpack. Food for thought. Lots of options. I found I could easily use the rear zipper pouch without twisting myself into a pretzel. As the subject suggests, this rig made me totally reevaluate my pouch choices. It's no longer convertible back into a split rig for me. If you're starting fresh without previously using a 34A as a split chest rig I would recommend buying some very cheap surplus pouches and once you figure out how you want them, buy Spiritus stuff. Only possible negative I can give this kit is the price being about $70 too expensive, but after using it and enjoying it I think it was worth it. No lost stars for being poor
