11-30 rear(8X) 22-36 front(2X) w/ Sachs(SRAM) Quarz DIRT short cage. Will this work? I have some LX splined front cranks, will aftermarket 36 front middle ring fit, or am I stuck w/ what shiman gives me? thanks!

If you're suspicious of the SRAM, a Shimano short cage road derailleur is another option. The DIRT will work with any non-ESP (i.e. Shimano, SRAM Attack, Rocket or DIRT) shifters, and is a solid unit (definitely better than their DIRT shifters, which I didn't really care for). I referenced the other post you linked to, and to be honest, I wasn't aware there were multiple versions of this derailleur. And so long as the 36T ring has a 104mm BCD, you're golden. Your choice of an 8 or 9 speed chain to work with that combo: either will shift fine on an 8 speed cassette and I don't think you'll run into any trouble running an 8 speed chain on a 2x9 setup, even if it's a "9 speed" ring.

I know at least Black Spire makes a 36T in a 104BCD. No shift pins but it's a bit more heavy duty than a Shimano chainring so it should hold up better...

Without a big ring or extra low cogs, you don't need the capacity a long cage offers and a short cage should be fine. I had an SRAM Plasma DIRT derailleur that looked more like the one Davide had in the post you reference. The picture that Cambria had looked ancient, more like an old Shimano roadie derailleur. If you're looking for cheap, you can probably pick up an Ultegra 600 or 105 for next to nothing on eBay.

Thanks for the info guys, Cambria actually had one of the long caged Quartz which looked like the one from the other post instock. Picked that up and will probably look for a short caged one later on. I'll stick w/ the 2X8 idea since I don't really use the big ring much, i'll just leave it on as a pseudo rock ring.
