Racket head size

[Bobs tennis]

I have been playing with gamma big bubba's for some time and basically happy. A while back I started looking at the wear pattern on my frames and felt the wear is all in the upper center of the strings. Borrowed a friends 105 sq frame and frankly it felt fine. Serve was slightly weaker but everything else was maybe better including volley. Truth be told i'm definitely a senior but questioning racket head size
