Is your derailleur clutch ON or OFF in your photo? I've played around with mine being angled like that and have been worried if left in the ON position there would be too much tension and I might snap my chain as soon as I road over a bump.
Just installed the Garbaruk 1048 XD cassette with XTR MD-9000 (GS medium cage). Works with no problem, the B screw just a bit more in, and adjusting the top stop a bit. Exactly 315 grams. I ordered the Garbaruk Cage mod at the same time (it is an extra $20 or so) just to be on the safe side ... I guess it might be on sale now!
