Colt McClellandI think you've noticed right off the bat one of the major issues with OJ's.  I have a handful of OJ's and just started collecting them in the last year or so.  In my opinion, image quality is everything with an OJ.  I will take a nice bold image with good contrast but weak corners or back damage over a technically higher grade OJ with a faded image all day long.  
To answer your question, my best guess is that if you buy a card with a nice image and keep stored well without much exposure to direct light it will hold its image fine.  That's just my guess though, as I have only started collecting OJ's in the last year.  I would really be interested to hear what the old school OJ collectors think about this issue.
