Poly Plasma has almost no tension loss, excellent ball control, and is spin friendly.

This String was the first big development from Signum Pro and really made a big change into the tennis String Market, providing Tennis Players with a String of higher level that would produce good results for Competitive tennis players.

This was a new beggining for Signum Pro and this formula discovered by Bernd Gruttnet changed the results of many players for years to come.
