Bias is a whole other question, and one I think is more likely to be relevant. But you wouldn't be looking at Anna and the like if bias levels concerned you.

I'd agree that the effect of this is more likely to be responsible for the fairly consistent qualitative differences people describe having compared 9 & 12" arms. In my own experience those aspects are even more apparent on some airbearing LT arms although often at the expense of some other aspect such as LF quality. Whether that shortcoming arises because of the high lateral mass most LT arms present or because of the air bearing itself, I really don't know.
