Can you tell me how you setup this automated switching?
CryptoSwitcher will do that for you...had it running when I just had BFL miners, but it should work with these just as well. The only snag is that other sha256d coins usually won't make that much more than Bitcoin (right now, PPCoin will net you 18% more than Bitcoin, but that's before you exchange it).
Yeah, i found that software after i had written my own. It usually goes like this, if i get an idea about something that would be nice, someone has already thought about it and propably implemented it

. Well it wasn't complete waste of time, learned Python3 doing it and it works. If only i had more time to implement some nice guis for monitoring miner speeds, current pools and editing configs...
