hehehe, yes my thoughts too. i'm only ever so slightly bothered by the yellowish tint but on the other hand an uneven coloration or streaky results would definitely be much hard to get over.
I was already leaning on the conclusion that this is just its age and part of it.
and actually the board inside my head discussing this topic was overwhelming majority in favour of not doing anything. and just to try to convince this one single board member who wanted to at least find out more, i went ahead and wrote in this forum about it to have more people weighing in. so your opinion, along the others, was also very helpful : )
