I've played with the Becker 11 Mid. And really enjoyed it as well. Have since moved on. Recently picked up the Becker Melbourne. Was going to recommend that until I saw you didn't like the 18x20 string pattern. What is it about the 18x20 that you don't like?
As for the Melbourne, I've found it to be super solid at net, offers me plenty of topspin and Maneuverability hasn't been an issue at all, and it offers plenty of pop with the right string combo.
The only caveat that I've heard regarding this racket is that some find it too powerful or find the string bed to lively. This hasn't been an issue for me however.
