Difference between Tenergy 05 and 05-fx

Hi Coach Alois . I am using my tenergy 05-fx on my forehand side and I'm thinking what's the difference between tenergy 05 and tenergy05-fx  . Should I change my forehand to tenergy 05 ? I'm using this on my Butterfly Sardius . Thanks :)

Hi Paul,

The 05 is faster and harder.  If that is what you are looking for with your forehand then it may be worth changing.  Otherwise, stay with the FX.
