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.
