Bluto - You'll be fine. Most of the guys jumping on the "8.8's stink" bandwagon have never run an 8.8, and only a few have seen 'em fail - in person. The tubes should be welded, but I havn't gotten aroung to it, and it's held up fine to 35's and hard wheeling so far. Who's SEEN the c-clips fail on the 8.8??
I'm by no means saying that D44's are crap, and 8.8's are the best. That's pretty arrogant. In fact, a Dana 44 has better clearance under the diff than an 8.8. - which is clutch. Part of the reason I'm casually toying with the idea of at 44 swap front/rear with waggy 44's, for a little more width, and a litte more clearance - just a thought...
