I would say between those two grinds.
The GR8TR is very fine and the NVFG is slightly coarser than the Diamond Cut. For my use it is a perfect grind and starting it upside down gives an even finer grind. — lazylathe
I can't understand grinding upside down — Futurevapors
$99 CAD is the price! — lazylathe
My Lift grinder is far inferior to the Diamond Cut.
I like its technology but in my opinion they can still improve it more. — lazylathe
