Currently use a Prince Speedport Black - Love the racket as it's a heavier head weight but with a lighter swing weight due to the airport holes etc.. Used it for years and have a fairly average game. I sometimes struggle with control when going for the winners however (like most people!!!)
Either way, haven't thought much about changing but my club had a Head demo day and I tried out the djokovic youtek racket for fun which has a much heavier head weight. When I picked it up I even though "wow" and didn't think I'd be much good. To my surprise, when playing, I was so much more comfortable with going for aggressive shots and found the results quite surprising. I enjoyed playing with it, felt comfortable, and could add extra power to my swing for better deeper shots without seeing the ball flying out.
I did start to feel it in my arms after about 20 minutes of consistent hitting however. I'm not the fittest/strongest in the world and as I work (a lot), putting in a lot of time and effort to improving my cardio/strength is rather difficult. So the questions:
1) Should I upgrade
2) If I upgrade, will I struggle with muscle injuries till I put in the work to build up my muscles or will this come natural while playing?
I play 3 times a week ish at a club and semi-competitive standard (4.0 I think would be the USTA equivalent rating though I'm in England!)
Thanks for any advice
