Hey Roy, you did say 'All comments welcome' so please don't take mine as insults, just my own opinion. :wink:
I don't think the pic is up to your usual very high standard. This could be why there 'appears' to be some cloudiness esp in the cap. There seems to be a couple of adjoined spots that look like air gaps.
I'd be amazed if there was, because I have some blanks from the same source and they are absolutely superb.
