I have been doing several hundreds of jumps on it now and am very happy with it. Answering questions below
durability?
No problems, so as any other rig I have owned.
comfort?
Top notch. This could be the very best feature of the rig. Came from an Icon rig, Aurora is soo much more comfortable to wear. In the air, the deployment flying a wingsuit is a breeze. You can also place the PC in multiple positions, so put it where you like. Personally I put it next to my back, so around the corner towards my back. There it lies well protected and super easy to grip. The neoprene collar up around the yoke is in fact removing air travelling btw the rig and your back - when going fast aka diving. Gives you a more calm ride, at speed, especially at competitions.
ease (or not) of packing main container?
Packing, you have to learn it, but for me it was quick. Packing is much easier this way I find. Relaxed, spend much less time deflating the canopy, it doesnt matter too much as you will form the bag, once it is closed, with your knees
does your rigger swear at you when its time for I&R?
No, its just a Jav...
harness configuration (rings at lateral / leg strap junction or other)?
Tie downs (hip connection) are adjustable which is not needed really. So I got advice from Sunpath after complaining about them moving having to be adjusted every jump, to let my rigger stich them on a preferred setting. Done. Happy now.
other?
In general I am not a big fan of the Javelin reserve container system; I take issue with the "weak" reserve PC. I like a stronger spring really - get the hell out there. The weaker spring is okay if you are blasting downwards at terminal speed. In a wingsuit situation you are in a different situation completely and so I would have liked to see Sunpath acknowledge that fact. I spoke to them about it of course. Anyway, if Sunpath announces an upgraded and stronger one, I shall order one.
