Head Graphene 360+ Radical Pro v21
As you would expect the Radical Pro is the heaviest of the Radical Series, but only by a few grams! What! When we talk about grams to some players it might as well be angstroms or something like that. What the heck is a gram? For many in the US market is still “Talk to me in ounces, please!”
OK, there are 454 grams in a pound and 16 ounces in a pound. If I said a racquet weighs 285 grams what would you think? Or, if I said the racquet weighs 10 ounces which sounds better if you are weight averse?
OK, the Radical Pro weighs 13 grams more than the Radical MP so how many ounces is that?
Enough of this stuff! However, it is important to know what weight is and how it can be a significant factor in your playing. Weight is your friend!
As you will see in the following specifications a lot depends on how the weight is distributed throughout the racquet.
Here is a little hint; take a look at the swing weight of the MP and the Pro and tell me what you see.
The Radical Pro has the “sound grommets’ and the “control pattern” for those concerned with string spacing, and that should be many of you. String spacing can have a profound affect on durability and playability.
The enlarged circle was intended to show the elongated grommets which allow the string to move and effectively be a little longer meaning more energy return.
