Head Graphene 360+ Gravity MP/Tecnifibre RPX
Normally our racquet reviews are when a racquet is brand new; however, this is a case where the updated string, RPX, from Tecnifibre is an excellent opportunity to add another review to the site!
There are some excellent reasons to review the same racquet again with different string or tension settings.
- It allows us to evaluate new strings for comparison purposes.
- It will enable the player to demo the same Racquet with a different string.
- The string can affect the overall weight to a small degree but significantly impact swing weight.
For example, this racquet with Victrex 7718 PEEK string (15.9grams installed) has a swing weight of 318. With the new Tecnifibre RPX (18.0 grams installed), the swing weight is 325. That is not huge, but it is different.
Lead tape, commonly used to increase swing weight, weighs in at 2.8 grams for 12 inches! So, slightly over 2 grams of additional string weight in the strung area contribute to the difference between these strings.
Of course, this also means that swing weight can be reduced, somewhat, by using lighter string! We weigh all of the string we test for Power Potential, so we know which string can benefit either swing weight preference.
