hi, I would like to know which racket is a better quality and better racket overall. The Myoga Issen i think is around 180$ while the Vortex Radon is around 250$. However, I'm not sure which one is the better of the two in terms of overall quality or for power player. Second, I would like to know which brand is a better brand and I noticed the Vortex series have 3 rackets. What do you recommend of the 3 rackets? Krypton XL, Xenon and Radon. Thank you.
