I've been using R09 for a little while now, it's very nice but I fancy a brew with a less grainy look, so I've been thinking of trying Xtol. However I understand that it has had problems wrt storage and 'sudden death'. Are there still problems with Xtol? Is Xtol worth the bother? I don't want to waste time, money or film, but I've also heard that it is very good. Thank you.
