Ashaway MonoGut String
I have been evaluating a new string from Ashaway, the only manufacturer of string in the US, going by the name of MonoGut. Nothing unusual about that except this new string is a PEEK monofilament! The trade name for this PEEK is Zyex™ and is unique in this construction. MonoGut contains no polyester component.
MonoGut has many of the advantages of polyester based string, i.e. string movement for increased spin potential, plus a very low coefficient of friction which should make if last longer. However, there is a more important characteristic and that is a very low dynamic stiffness. That means the string is going to be very arm friendly.
I will publish more as I get closer to collecting all the data I want. This could be a game changer!
