Comments: Totally awesome string, especially in the 17 gauge version. Tried both as a standalone full bed on my Radical, and as a hybrid in combination with ALU Power Rough (RF setup). For me, it has every bit of power and comfort as a Babolat VS natural gut, maybe just a notch stiffer, but that's not an issue if you drop down the tension by one or two lbs. It has some kind of a special coating which makes it more durable than VS, which is good because it's possibly one of the most expensive strings on the market (but worth every dollar). Great string and one of the best natural guts out there.

Comments: Compared to the previous Wilson Natural gut string, this version, though seems to last a bit longer, has less power and less tension retainability. It plays well when freshly strung, but looses tension rapidly thereafter. The previous version priced at nearly $55 competed head to head with the Babolat VS 17, albeit with a slightly softer feel. Whereas this latest version of Wilson gut is considerably cheaper, which might explain the above observations.
