If you're busting axles like that, what are you replacing them with? These?

After reading this, I'd get my driveshafts replaced pronto if I were draggin'... especially since I would not have any support staff or tow vehicle with me.
As far as the tranny goes, are the Neon's the New Venture design? What's so special about the Getrag's? A technical comparison article on these trannys would be helpful.
Finally, popping the OEM clutch gives me the creeps. What's a mild drag yet streetable upgrade with a billet flywheel? I see Howell has several.
