Have you tested any??

I know that Gary Hand tested some of the 10 inch F5 mirror a couple of years
ago and reported them to be 1/10th wave.

I have had some private correspondence from a well known mirror maker who told
me he had done some observing with an XT-10 and found it excellent...

Uncle Rod seems to be quite happy with the Optics in his 8 inch Konus
reflector...

Your calls of BS may indeed be true but without any backup and with there being
some evidence to the contrary, some test results would be in order.
