My understanding is that the D & C specs are backwards compatable to 
B and A.

I don't know anything about this, but I suspect that synthetic GL-4 
would be AT LEAST as good as dino GL-4. I've only heard good things, 
too, but, like you, I don't have any first hand experience with any 
of it. I doubt if the brand makes any significant difference.
