I had strung the Touch Turbo at my usual tension, which turned out to be a mistake. The string felt a bit stiff. Control was ok, but I missed the touch and the turbo...
With 1 kg less, the real characteristics of the TT showed up. Lots of power and touch, but you have to be able to control it. At somewhat lower tension the TT is quite comfortable to play with. Tension stability was ok but dropped rapidly shortly before the string broke.
-> 1 kg is about 2.2 lbs
