"I've read/heard people say the same thing too many times for me to want to use .spcl cases.................."
While I don't doubt Tazman encountered a problem; I've never been that unfortunate. Whatever the issue is, I've never experienced it.
As for reading & hearing things - I've read and heard about bigfoot, mid-Atlantic cougars, opportunities to purchase the Brooklyn bridge and many other things. Reading and/or hearing something is hardly the threshold to establish something as legitimate.
Now maybe there is some unusual combination that can cause some difficult to remove debris but I've never come across it.
