During 2 seasons the "rotating strap system" has been on the market, mainly for directionals. The system could be used for "mutants" too, but users asked for better pads.

Well further development lead to the "Dedicated TT version" with multilayer EVA pads. The new version also fits plug distances over 137 mm, which means all production TT boards.
