Head Gravity Tour 98-Pre Release Version
If you have listened to our latest podcast, you will know a little about the new Head Gravity Tour 98, to be released in January 2025!
The difference between what you may see online and what Racquet Quest, LLC has is we have taken a raw racquet and applied the desired specifications to it.
We see this as a racquet suitable for many playing styles and levels, so we began with a swing weight of 321 and an overall weight of 327.
After Stephanie’s brief video about her reactions to this Gravity Tour 98 racquet, we will return to associate her comments with the numbers in our review! Wouldn’t that be fun?
In Stepahines’ video, she adds several years to the age of her Gravity MP, calling it 2003. Actually, it is 2023.
Now, here’s Stephanie!
