I shot the new Switchback at the ATA Show this weekend. Very quite, fast and smooth. It is a mix of the LX and Outback, if that helps. I really liked it and should be getting mine in the mail really soon. I have to say (since I shoot for them) that it is worth the upgrade, go buy one right now! My personnal advice is go shoot it and see what you think. It's a little faster and let's off a little further back, which is how they got some of the extra speed. Not much creap, if you know what I mean. I really liked it though, I shot the LX last year and didn't even take the free Outback!
