If you wait a few days, I will most likely be able to compare them side-to-side. It is pretty thin, and since I play mostly rhythm, it was too thin for me. And it's even thinner at the upper frets. It IS a shred axe... But the neck profile is too subjective thing to judge.

And since it's both neck-through and V-shaped, I can't imagine what can possibly go wrong with upper fret access. It's very light and comfortable to play... Although I haven't tried to play it sitting down.

AFAIK, compound radius means that it wider and more flat as it goes up the fretboard. They are made like that in order for the bends to not fret out up high... But it can also serve other purposes.

I played a Japanese RR24 in the store - the neck was nice and smooth, but too thin for my taste (neck profile on the B.C. Rich neck-throughs is perfect for me). And compound radius is a plus, as long as you get used to it.

That Jackson also had pretty low action... I constantly hit the EMG cover with pick when playing. And overall, the guitar felt too small. But I would have bought it if it was new and a little cheaper than the store wanted.

I'll be in the same store to check out stuff in a few days, and I'll be sure to molest it some more, as long as no one has bought it yet.
