I'm currently using a JS12F which I find to have too thin a grip. My go-to is a Victor towel reel, but I end up wrapping it twice to achieve my desired size. However, it makes the racket feel head-light. Any suggestions? Our shops here dont have the cushion wraps.
Yehlex make a very thick, high quality towel grip. I have used it in the past. https://www.yehlex.co.uk/collections/grips/products/yehlex-towelling-grip-39-coil
