Yeah, if I decide to do it it would be only out of boredom. CM7 has been so smooth that I haven't flashed in months. I'm leary of rumors that say that perhaps if you flash the soak test it might not allow you to SBF to another version.. This was on the DX though, but again, we'll see.

Flashing rule to live by: Always remember to wipe Cache and Dalvik Cache!
