Update: My bass was ready today, so I got to try this out!!
The bass got painted faster than my parts are in, but when I went to go pick it up today I asked Pat about it. He welcomed me to play it out, which I gladly did.
Overall impression: 30.5 scale is VERY comfortable. Body is nicely weighed, not too heavy at all. No real neckdive. Amazing tone. Barky J-bass to smooth P-bassish tones from the neck pickup. Dunno what pups/pre he put in there, but Pat done right! We talked about him as a builder, and I played out one more of his basses (A 5 string MM/J) with Nordstrand pickups. Damn that bass was loud acoustically, and just felt great.
Very cool cat, very cool basses.
And a cool lil' factoid, this bass fits in a guitar gig bag, so you can take it onto an airplane in the overhead. Yo.
