Like I said before, I doubt that any improvements audible with heavy pressings are actually attributable to the vinyl weight itself, which I regard as mostly a marketing hook.
However, I'm inclined agree (from limited experience) with those implying that heavy vinyl may actually *cause* a higher incidence of warps in new records. Whether this is due to greater difficulty of the manufacturing process or is the result of heavy pressings being less able to flex and recover well afterwards I don't know. I've even speculated that thicker records will suffer more from a side-to-side temperature differential when subjected to heat or sunlight that could promote warping vs. a thinner record.
Whatever the reason, when it comes to extra-heavy pressings it's indisputable that once warped they're tougher for clamping-out the warp on the platter, so even if the incidence of new warpage were the same for all weights of vinyl, it would still be more problematic with the heavyweight disks.
P.S. - Pbb, when one is out trolling, methinks it unseemly for a mere mortal to attempt the creation of one's own fish. It's much better to wait to exagerate until one has returned safely to the dock.
