I played with the 11mid for about a year. I loved it for its feel, serving ability and power. In the end I wanted a larger head size and a little less swing weight.
I don't feel that either the London or prestige pro offer this.
I agree with the pacific (I played with the fisher one) or possible the C10 (though only from what I've read on tt). I recently switched to the donnay pro one and it may also fit the bill. it is slightly more powerfull than the 11mid with all of its qualities.
