We still use the flat pads here at my shop in Boulder, and won't change until they wear out. I'd suggest the same to our customers, as the new pads were a slight improvement, but not one worth breaking out the Credit Card for, not until you kill a pad, or after 6-10 uses.
My $.02:thumbsup:
So the Pads only last 6 to 10 uses oops! I 'm ordering now
