I've used this string exclusively for about 4 years now. I like the balance between the softness of the gut and durability of the synthetic. I string the gut on the mains and the synthetic on the crosses to further decrease vibration and increase power. Try decreasing the tension on the gut 2-3 points lower than your synthetic to keep a better balance longer.
While a bit pricey, I love the feel the natural gut gives and the control and spin provided by this hybrid...I'm a placement type player, prefer net action, not a baseline player, playing three times a week.
