I have two AMD 6000 series rigs and have switched over to 1.56 late yesterday on crazypool. I'll let it go a few days and then run a comparison on pool side stats for shares.
Crazypool doesn't pay for stale shares and is not a recomended pool for The Team Black miner. You might need to reduce the default xintensities to get fewer rejecs/stales.
