Is Oren correct in stating that chemistry, not HP5+ itself, is going to emerge that will alleviate the pesky shoulder problem? If so, why didn't you just say so in your original statement, rather than wait for an interpretation from someone else? This ULF film thing is driving me crazy, because so many people (not just you, Steve) find the need to leave tantalizing, cryptic messages about "possibilities". Why should information be so proprietary? Aren't we all trying to work together to become a market for the film manufacturers? If someone knows something and feels the need to share it with the community, then, out with it, please, and spare us the anguish of endless speculation.
