So...I going to a new stringer who is willing to order anything I want. To tell you the truth, I don't know much about strings. Currently, I've been using a hybrid with Head Ultra Tour 16 gauge in the mains, and Babolat XCel Premium 16 gauge in the crosses. I'm a baseliner, grinding type. Can some of you M-fil 200 users chime in and tell me some of the set-ups that have worked best for you? Thanks guys.
