That's what I do with the capo. I often find that mashing it very hard right up next to the fret works well. But I do have the groove as well.

Tuning on the 12 is actually sometimes easier than the 6, once you get used to it. All those doubled up strings make it easy to find a note to tune to without getting out your tuner.

I absolutely agree with you about the action. Nick's guitars work well with a gentle touch so you don't need high action. And you a lot more with a lot less on the 12.
