here are pools that still support direct ORB mining and are synchronized correctly:
yiimp.eu (2% fee, min payout 0.01 ORB)
aikapool.com (1% fee, min payout 1 ORB)

multipools:
mining-dutch.nl (2% fee, min payout 0.0001 ORB)
zpool.ca (1.75% fee, min payout 0.05 ORB)
zergpool.com (0.5% fee, min payout is equivalent of 0.0001 BTC)

do not use TBF pool. It is not correctly synchronized (more than 3 months now) and it is unable to change/set payout wallet and limits. Pool operator has not fixed it yet.
