glad you found a tension that works for you.I took your advice and added three cotton balls to butt cap. Such a small amount of weight but it makes a big difference. I strung it with RPM power / excel hyprid a bit low at 48/51 but it plays effortlessly just need to add top spin , serves are amazing
just be aware that as the strings lose tension it may get mushy and you may not have the same control
especially in summer.... you may want to go up a couple lbs.
I'm playing around with tension myself!
glad the cotton ball trick worked for you. simple but effective.
