It arrived the other day, and last night I got it up and running, using (temporarily) a pair of Gibson humbuckers I had laying around, and a Tune-O-Matic (with the big mounting holes, it's a really loose fit, but it seems to stay in place just from the string pressure):
Despite the pickups really not being my cup of tea, it sounds amazing. One thing I always hear about Hi Fliers is how light they are, but this one is about the same weight as the heavier of my two Jazzmasters. I don't mind though, the weight seems to contribute to a solid and articulate sound, with very good sustain. I was a bit worried the neck was gonna be too thin and narrow, but it's actually really comfortable. It is narrower than what I'm used to, but it's not unusually thin.
I'll be replacing the pickups and the bridge with something more permanent as soon as I get the chance, but the guitar plays really nice as is, I can't put it down.
