I love G30.  And I don't golf.  I actually see it as an all-purpose lens.  Yes, it is a bit light for super-sunny days, but better than nothing at all... and it is quite wearable (i.e. not too dark) even when overcast. 
 
Best thing of all:  you can actually tell people you see the world through rose-colored glasses. 
 
I hope G30 doesn't totally disappear.  Prizm Golf is nice, but I have the same issue with Prizm that I do with polarization... it is almost too high-contrast and gives me eyestrain.
