Does anyone here have experience with both?? How would you compare them??

The most confusing part (to me ) is their listing of "fine-ness". While "officially" the translucent and black stones are listed as being the same, Dan's says the black are actually a touch finer where Hall's says the translucent stones are finer grit than the black. (and perhaps they are both correct for the stone they mine?)

But any opinion of either company would be great.

Thanks!
