Cooper recently bought Ocular Sciences, and they are "integrating" the
two product lines together.  I think "assimilating" is a better
analogy.  The line between the two product lines is getting quite
blurry.    (pun intended)
A lot of the Ocular Sciences product was slightly larger and flatter,
some was aspheric and some was not.  I think you are smart to not
listen to the company line and assume that "equivalent product" is
necessarily so.  You still need to trial fit the changed product, IMHO.
(in my humble opinion)
