Hi felken,
I can't really answer your question, I'm sorry to say. I commute on the opposite end of 205 every day. From what I hear on the traffic reports, it sounds like a moderately congested drive - not the worst but not the quickest drive, either. Sometimes things get backed up on the I-5/I-205 junction (which is the way'd be going from West Linn to Wilsonville), but you may be going in the opposite way of the majority of people, who are probably heading toward Portland and not Wilsonville. West Linn is a very nice area and Wilsonville is really growing, I'm sure it's got some nice residential areas, too. Sorry I can't give better info! Good luck.
