I use this one and i like it a bit

hs->bloodbath->Maim->unchained->SE->HS->berserk->SS->BB->Internal release and vengeance->HS->maim->SE->fracture->IB->IB

With this rotation unchained ends right after fracture and before two IB, so your aren't wasting it, you can also use second wind after fracture and you will probaly crit is since it's affected by wrath stacks and internal release, in this way you can maximize autohealing and if you are a bit lucky(crit on second wind and both ibs) you can heal yourself for over 3k hp in 5 seconds.
I sometimes ask myself what the prepatch war would be with this combo, it's like 7k or so of autohealing, fuck healers
