Excellent !!!
[I am sorry to hear of the "Vivitar 90-180 flat field zoom failure", though.]
I await the results with bated breath . . .

I have thought, based upon my own experience over the years with a number of dedicated macro lenses (from 50mm to 200mm), that you just can't buy a bad 100-ish macro lens.
My current most-used macro lens line-up is the A 50/2.8 Macro, the Tokina AT-X 90/2.5 Macro ("Bokina"), and the Vivitar 135/2.8 Close Focusing, but there are many, many other great macro lenses out there. and, as for the concept of other "differentiations":
The A 50/2.8 Macro is not the sharpest 50-ish macro available (certainly the F and FA 50/2.8's are a tad sharper), but it is sharp enough, and is ~so~ much nicer to use. [I used to worship only at the Altar of the God of Sharpness, but I since have grown to recognize that other parameters can be quite important, too.]
The Tokina "Bokina" is incredibly sharp, but so aren't many other 100-ish macros -- but it is just so delightful to use. [The VS1 "Bokina" is even slightly nicer to use, if one doesn't mind "green button" metering (and if one is willing to be more careful with flaring) -- some (but not all) Tokina 90/2.5's come in convenient Ka mount trim.]
The Vivitar 135/2.8 Close Focusing is just wonderful to use, even if it goes to "just" 1:2, and even if it requires "green button" metering -- it is just so sharp and contrasty, and focuses so nicely, it's simply a delight to use.
However, none of the above three lenses go to 1:1 (all go to 1:2, although the "Bokina" 90's have extra 1:1 adapters available), but I rarely need that much magnification, so that's not a "differentiation" that's important to me (YMMV, of course).
But, there are just s-o-o-o many good macro lenses out there -- aren't we lucky for that? :)
