FWIW: Mining is simply a hobby for me so not getting paid for a few days hasn't been an issue.  (I have always received full payment eventually.)  As long as the pool continues to pay above what I can find elsewhere, I see no reason to pull my miners.  I've been mining here since last August and despite a few hiccups, delayed payments and such, I'm still way ahead of what I would have received elsewhere.  (IMHO)
