I was wondering if anyone knows how to find the optimal tension for you? I currently use 30lbs but am scaling it back to 28lbs as my shoulder is not what it used to be. I am not able to smash without feeling like it's dislocating. I also break strings frequently so cost is a factor.
What signs, factors do you use to decide tension?
My test for my own upper limit is just a shuttle speed test: if I can hit an underhand shot from one baseline to (at least) the opposite doubles service line, I consider that tension within my capabilities.
The lower limit is tougher to define concretely - net spinners are a good gauge.
I've played at 22lbs for a long time and it seemed to be my "sweet spot" for tension, power wise anyways, but I felt that it was lacking some "crispness". I ended up trying gradually higher tensions (23,24,25,26 lbs) and it never felt quite right. I didn't want to go over that because other tensions seemed too high for me.
And then one day, I tried my friend's racket at 28lbs. I expected to not even be able to clear, but I LOVED the feeling and felt I had even more power than with lower tensions. I just assumed that I felt great that day and kept stringing my rackets at 24lbs.
I did the experiment again this week, this time with the same racket. I had one Flash Boost strung at 23lbs, one at 26lbs and the other at 28lbs. Again, the racket at 28lbs seemed to be better for me. More power, more crispness, more precision, I simply loved it.
Maybe the effect is psychological, but I'd be surprised since I liked the racket at 23lbs, then picked up the racket at 26lbs and it didn't quite feel good and didn't play well. When I picked up the racket at 28lbs, I thought that I wouldn't be able to generate enough power and that the game would be horrible.
Games aren't the best moment to compare rackets or tensions, but it is a feeling that I got all night after switching rackets.
So I'm thinking, would it be possible that we have 2 "sweet spots" for tension ?
My guess is that the FB requires a whipping style of play and that you're able to generate faster racket head acceleration with it, as compared to say VZTF. Hence you
find you need a stringbed with faster rebound time.
Another factor I've just found out is the type of string you use. I had been using a .66 string which kept snapping. My record was 20 minutes. They have now been thrown in the bin and 2 different types of .68 have been put in. My conclusion is .66 stings are not very good at high tensions.
