For tahiti and Pitcairn it seems still 9.7 is fastest 
Very good speedup on Polaris!, 20-30h/s per card or even more

Hmm, in my tests v11 is a bit faster for both Tahiti and Pitcairn, or at least the same. May be you use not optimal settings.
still no support for old HD 7700/7800 cards 
(don't say anything about 9.7 version please, which doesn't have magical "-allcoins" option)

Sorry, I don't not support very old cards anymore.
