wah, this is as correct as you can get. The Cayman S is D-cup and the Cayman is A-cup. KORRECT!
Depends on you, whether you're a D-Cup man or an A-Cup. I have always like A-cups for close company and D-Cup when I go for a lap dance. Difference is this is the girl you're marrying, bro. D cup really always get in the way and also sometimes she complain that her breasts are so heavy that her cooper's ligaments ache lah, etc. (hello, not Mini Cooper OK? Dr. SM Yuen can tell you that the cooper's ligaments are the things kenna strain holding that few kg of breasts)...
A Cups ... well, they make sure you don't confuse that this girl is a DUDE, but yet, not so big as to be in the way. This girl can go with you for runs, hiking, everything ... and at least people don't stare at her D-cup all the time ... A-cup being lightweight and fun ...
In any case, the champange glass (coupe) is usually the measure of the perfect breast, (
Urban Legends Reference Pages: Champagne Glass Origin ) , nobody has ever claimed that you need to use a Cold Storage plastic bag to test for good breast size.
You want the show or you want the real fun?
