After checking into the physical properties of Corecell A550 plain it looks like it may be a good alternative to the Divinicell I was planning to use...that is if I can find the close supplier and the cost is in line. So far "Noah's marine supplies" is my only find, and they are in New York. Merritt Marine supplies is my Florida connection for Divinycell products...and they do carry some Corecell products, but not the 9.5mm A550 plain.
