I've seen both Livia, excellent, and Alessandra, both away at the moment I think.
Totally agree with you, Livia was fantastic and will hopefully be back soon. Was working from a flat in central Cambridge when I saw her just before Christmas. Alessandra on the other hand, good owo, cim and kissed but just laid back, hardly moved to the extent I wondered if she had some sort of paralysis. Put sod all effort in and round 2 she told me ok you go on top, again she just laid back. She did say she was packing the game in, won't be missed too much !
Haven't seen any of the others you list so can't help there.
