So, it would appear the Tosca ate another rear derailleur ... bringing the body count up to:
- 2006 XT rear derailleur: catastrophic failure (explosion on Queen Street).
- 2007 Deore rear derailleur: pivots blown (5mm of play).

Remind me of this next season when I'm second-guessing the whole SSCX idea. Also remind me that I bend my derailleur hanger on what seems like a monthly basis (and that I'm tired of that **** - tired, tired, tired).

Also, how do you quickly go to the end of a line when you're editing text on a Mac? Or back to the beginning of a line for that matter? I have mere days to figure this out! And wait, what the ****?! How do I use the "Delete" key like ****ing delete? It's going all "Backspace" on me! DAMN YOU, STEVE JOBS!!!
