I somehow picked up the habit of bringing the engine right down to the point of stall when I ease off the line. Not sure why, but you'll see the nose drop then pick up when I drive. I need to stop doing that.
Per the 2-rev thing, I don't see it a lot at the subaru meets. I know I do it sometimes however just to get the car rolling. But I try not to slip the clutch too much. Also, keep in mind that with an AWD system, you can't chip the tires to relieve driveline shock like you can in a 2WD car. So you have to drive with that in mind.
As for Audi-vs-Subaru, I'd rather the ease of working on a Subaru, lower repair costs, and diffs that are actually LSDs rather than using the brakes to emulate them. And I couldn't care less about having a great interior over a good interior. But that argument's been covered countless times already.
