Interesting. I had a jackson reverse headstock guitar and I can't remember the model, but it had the best thin D profile on earth. I actually thought it was much better than the Ibanez wizzard , super wizzard, etc, in my humble opinion. It was thin, but had just enough meat on it or something. Hard to explain of course. I have a Jap Charvel that's just like that in the neck and I love it. It has a Hum in the bridge and single in the neck and a schaller floyd and reverse headstock / jackson type and sounds great also and has that same profile, although not quite as nice as I remember the jackson being, but that could be because I was so shocked at how good that thing was. The best neck profile I think I've played was the EVH wolfgang version which I guess is Asymetrical and I thought it was perfect. It is bigger than some may like but for all around playing it was hard to beat. I might have to do that on the Musikraft neck I get also!
Thanks guys.
