Michael,

I'm in total agreement with you with ragard to the wire test.   Built mine
in '80, it has trained both of my eyes over the years because the wire test
*teases* you into using one then the other the beginning, at least it did
me, so now I'm only half subjective.    It rounds out the TM. (chuckle).   I
also use a "double edged"  knife for spheres.

So first I test the mirror, then "I" test the mirror  Then we
crank up the Vavaldi a great time is had by all!
