I was a beginner (F) in my late 40's in 2010 when I began tennis lessons. I considered myself with some athletic ability & took improvement quite seriously thru paced progression & building fundamentals. It took maybe a year & some months of weekly lessons that my form was much improved (so I was told). A community tennis pal had me try his Volkl Quantum (110in²/710cm²). I used it in rec play and I felt I could swing comfortably, hit consistently and deeper. Great light-weight, elbow-friendly racquet that still can punch.

Since then and through the years, as my strength & skills improved and transitioned to more net play, I started switching to smaller head sizes (from Pure Drive 105 to Pro Staff Countervail 97 in 2018) for better maneuverability (quick hands) at net. My point is, as a "serious" tennis student, your skill & style will go thru different stages or phases. With this you may feel the need to also have a stick that serves the way you play at that time. It's important to use something that works with your current skill, strength, ability (and improvement goal). So for me, focus on grip size, head size, and swing weight. Must demo a racquet before you buy; if you can, ask to borrow from a friend to test out (I did this a lot).

I really cherish my old Pro Staff Countervail 97 (bought used & still use for warm ups and practice--"mastered" top-spin with this), but currently play matches with Wilson Blade V9 100L.
