That may be it. I think Ibanez did the same type thing at one time or another too. I haven't been doing a lot of guitar repairs for a while, by choice. Amps are more fun - lol - and working on guitars kind of Led Zeppelin'd to amps I guess...
I sound picky when I'm buying a guitar because I want it made correctly - so the guitar can be set up properly, possible future work/repairs, etc. But, once I know the guitar has everything where it's supposed to be I'm not actually the pickiest person in the world set up wise, when it comes to my own guitars. If something bugs me when I'm playing or starts to bug me I fix/change it
Nut wise, for me, I generally bring it down to where the first fret is on note (with my finger pressure/style), maybe a tad past in case I get a bit Hulk Hogan'ish when playing, and generally like them all the same height. To me that's a personal preference and there really isn't a right/wrong if the person playing it likes it...
