Whether PCA is a good idea for your problem or not is a very
complicated question, which will require a book length answer. This is
an investment that most people on the list are not willing give. After
all, that is what libraries are for.

My take on PCA is that it is a very mechanical un-theoretical
technique and you should take that into account when talking about
"performance" or "fit".
