My turn for a mini rant. I don't object to heavier vinyl, but if you are gonna make the vinyl thicker, for Pete's sake, press deeper louder grooves in it like the 80's 12" singles from Europe. If you sell e a 180-200 gram record and the first time I slide it out of the cheap, coarse paper sleeve it has static and audible abrasions like my US print of NKOTB(which was pressed like DynaFlex), then I feel like I have wasted my money and won't play it again. I change all inner sleeve to poly as soon as I crack the shrink, but still worry more about new records over older. On a different note, I don't get the problem with DynaFlex. I have an inherited copy of Three Dog Night's Greatest Hits. I know it went to parties, and it got played on a 78 needle(the one my Dad said lasted longer) and yet still plays great. I only find they slip on changers, which if it is an important record, I wouldn't play in a stack anyways.
