I don't see any fights being picked. There may be some tension, but I think both Jez, Gino and Matt have all been very polite to each other so far considering their past disagreements.
That said...
Gino if you are the only one who knows, well bully for you. The rest of us can't have a discussion regarding this because while I know what Jez' "opinion" is, like he said, you have not offered any indication of what yours is.
You said, "I can tell you definitively that the reason that there is texture/bumps on the cap/back has nothing to do with either the heating/cooling of the plastic, or with imperfecions, contaminants, or mold breakdown."
The only possiblity left after this is that the bumps were put there intentionallly, sculpted into the mould by someone...
So thats about it. I'm not picking a fight, just illustrating that this topic will go nowhere unless you give something to work with.
