The best thing of all would be to get a set with both perfect flow and extended improvisation.

But I stopped *****ing about that a long time ago. I'm happy to get either/or.

And if I had to choose, I'd rather get a tight, well-flowing set than a set with a couple nice jams punctuated by a handfull of pi** breaks (what can I say? I don't like to hit the "skip" button when I'm driving).

7/20 II was a great example of the former. I can't say I'll be listening to set I or III very much, but set II is definitely joining the rotation.
