I’m a 2.5 W playing for about a year. I play on a ladies league and practice many days a week. I’ve gone through many rackets, and I currently have a Yonex ezone 100L grip size 2. A Yonex 100 grip size 2 contributed to golfers elbow bc of very poor form, which is mostly better with the 100L. It is VERY hot where I live now and will stay that way until about October. I am sweating like crazy. I noticed lately my racket is twisting in my hand at the net to volley and sometimes at the baseline. Is this due to very sweaty hands or do I need a different grip? I struggle with gripping too hard - hence pain in hand/elbow and the constant shuffle to find a perfect racket/grip size. Thank you!
