WS and CenLink ARE a lot more aggressive on ADSL2+ though; I think that the VAST majority of COs/RTs on CenLink and WS are ADSL2+ capable. Not so with Qwest.
That's why I dropped Qwest. If they had stated they were going to be upgrading in the distant future, that's fine, or at least tell me that you're trying. Their statement of "broadband experience" that keeps people onboard baffles me. They showed no interest in upgrading my area (at least on the other side of the river) and no plans to.
