:yes:The problem is, once you've decided it's a "sales gimmick", you've categorized it as having zero value to anyone, and also pass judgment on anyone who chose to buy into it. That's where the logic disappears. There is no way on God's green earth a tire company, and now others, would invest the research into making dual-compound tires if there was absolutely no value to any of their customers. Perhaps the Pures are now what you'd call '2nd-generation'. Whatever... but since the tire obviously doesn't agree with your riding, it doesn't mean that the tire has no intrinsic or performance value to others.
My suggestion is, keep the judgment to how you have experience with it, and maybe shed light on how, where, why your failure took place. That's the way to help others with your experience.
Calling a technologic innovation "sales gimmick" doesn't help at all.
A sales gimmick is the application of orange paint into the tread voids in the tire as the "StormBringer" autobahn style-monster motorcycle (Kawasaki in formals) where looking at yourself in the mirror is what your after.
....and he knows sales gimmiks! He once sold me a hamburger an hour after eating an omelet for breakfast.
