Quick Q. There are some 763s and 762ERs that I'm eyeing up but because there aren't many good ones, I am considering maybe getting PW AND RR varients. How important is that? Does it matter as much as a/c types? Personally, I have never been one to be reckless or get any a/c for the sake of it but I really think it may be okay. Only leasing till '11-'15.
