My line of thought is like Scouter posted...
The page protectors take a lack-luster Mystic page to a bit nicer level,
and they keep the pages from pulling out. (Mystic pages don't have any
reinforcing around the binder holes like some of the fancy album pages
I have seen.) The page holes damage very easily. Also, the covers I have
been using fit the Mystic pages absolutely perfectly, no gap, no fold.
It sounds as though they can't really hurt anything, and seeing them
make improvements on the album pages themselves, I am going to continue
installing them a few at a time on pages that are either DONE all the way,
or pages that I don't expect to fill any holes on anytime soon.
Thanks for the input folks!
Gaff, I don't mind someone speaking their opinion loud and proud. I do!
I don't take it personal.
