Sorry, just again bringing up the profit switching capabilities that are out there. This is from AwesomeMiner.
External Profit Switching (for ASIC's and Antminers)
Awesome Miner will not add or change any pools on the miner. The profit switcher will only look at the pools already defined on the miner and change the priority of them. The priority is set based on profitability. The profitability of the pool must be known to Awesome Miner, either by using one of the supported multi-pools or by using a coin listed on the Coins tab.
I know this is what's quoted on the awesomeminer site but you can create your own pool groups and then assign that group to a external miner and set that up for profit switching. You just need to create a new profit switching profile. I currently have 8 pools assigned to my D3's through awesomeminer and it auto profit switches between 7 of them without any issues, prohashing is the only pool that isn't picked up by the profit switching profile. The only deal is when you reboot an external miner you have to add the pool group back to that miner once it's back online.
