Head Graphene 360+ Radical S v21

From our perspective the Radical S should be one of the most used of the Radical Series!

Head Graphene 360+ Radical S

Why?  The 102 square inch head size is optimum for players looking for additional power,( and who isn’t) in a legitimate players racquet.  We say “legitimate” because this racquet can be turned into any thing you want, now or in the future!

As you will see in the specifications this is not a really stiff racquet so it will be easy for many players to customize the string bed to suit current playing style with an eye toward becoming a more aggressive player, or not!

The Radical S continues with the “control pattern” and “sound grommets”.  We are not totally certain what the “sound grommets” do but sound is frequency and frequency can be felt so maybe the grommets are damping out some of the higher frequencies?

Anyway, this Radical S model is a great step into the “performance” racquet arena with plenty of room to grow!
