After all the discussion, I find myself amused that you finally opted for a 31T swap that is gonna give you a mere 3% gain. (which for most folks would be hard to recognize the difference). Here is hoping you enjoy it and don't regret not going to the 30T and a 6% gain that most of us have found to be recognizable and a welcome change to the stock gearing. 
Do you know personally that it doesn't make a noticable difference? The only one I know of that has a 2009+ and has ran both the 30T and 31T is Steve George. He seemed to switch to the 30T because he wanted more- he never said he switched because he never felt a difference. I tried phoning him to hear his thoughts on this, but we played phone tag and I never bothered after that.
Why would Andrews and Baker spend all the time and money manufacturing a 31T if nobody wanted it?
In any case, I made my decision based on the reasons in Post #162. As long as it helps the tall first gear issue, and makes it better in stop and go traffic, I'll be happy. Like I said, the 6th gear thing isn't as much of an issue with me, and I'm mainly doing this for the SE compensator.
I could end up liking it, I could end up regretting it-who knows. Guess I'll see what happens.
