Honestly I think both have their benefits, drawbacks and limitations, I have run both and would run either again. The only reason my Stauns are in the basement right now is I was holding out for a 2nd hand set of 15x10 DCII's which will probably never happen... I would offer mine to you (new coyote fillers thingies and tubes) but sounds like you're set up. My experience with the Stauns other than testing them out a few times was limited, that said I read alot! when deciding which way to go. Both options work a helluva alot better than nothing.
My external beadlocks are quite a bit lighter than 90% of the u-build kits out there. They are a self centering type if you put them togther right, (Sorry Bnine if I am getting what defines them as self centering wrong
) (but the square edged beadseats are a bitch but they do force the tire to be properly centered). They are not as strong as most of the rockcrawler intended types, I ran them on a couple different jeeps and other than the occaisional broken bolt I haven't had any problems (keeping in mind I have small HP motors (2.5 and a 4.0) and never ran bigger than 35's on them and I drive conservatively. They run less bolts (only 16) and the outers are made out of alloy, they are profile shaped, not flat and for the jeep you need 1/2 inch thickness, not the thinner 1/4" and have recessed countersinking for the hex heads, the weld on inner ring are fairly low profile as well. They are purpose manufactured for sprint car racing and you can get them from Bicknell Racing Products which I see now has a Canadian on-line store. mine are on a standard steel 8" D-window (not the two-piece rims they sell). Only complaint is the nice red anodizing faded to an ugly barbie pink colour over time, I had them painted black on my YJ for the last year but am repainting them red again. I also re-seal the welds with clear silicone whenever they are apart, couldn't tell you if they would leak if I didn't, probably would though. well that is my attempt at describing them technically LOL - some profile diagrams would really help but whatever you get the idea
The backside of the outers
faded, beaten and scraped up but still working great
Just assembled this one last night
