I have played 8 hours now with Tour Hex. Having played with Big Spin and T1 Firewire before trying Tour Hex, I needed some time to adjust to its characteristics. Big Spin and Firewire are triangular strings which create a special kind of spin called "kamikaze spin" by Locnetmonster. When you swing fast and with a lot of spin, the balls seems to sail out, but dives down at the end of the flight trajectory and stays in. With Tour Hex, this isn't the case, the balls sails out. But this is just different, not negative, because I could easily get a good length with Tour Hex, once I had adjusted to this phenomenon (which is quite normal, the kamikaze spin created by Big Spin and FW is the abnormal phenomenon).
I could play every stroke without problems and the string provided a nice, soft feedback and even a lot of power when I hit the ball in the sweet spot. So I think that Tour Hex is a solid and dependable string! It has no outstanding characteristic, but is a very good all-round string. IMHO, a lot of players may like it.
