I'm 46 years old and play at the NTRP 4.0 level. I enjoy as much of an all-court game as is possible for someone age 46. I prefer rackets that are 27.5", over size (105 - 110), and now I'm looking for something easier on the elbow!! Most recently, I played with the Prince TT Warrior OS. That played well for me but I found that I needed to string it around 65 to get the spin I wanted and to keep the ball from going long. But my elbow says "NO"!! So, my idea is to stick with the same basic racket dimensions at 27.5" and OS, but to get a more flexible & control oriented racket and even lower the string tension to about 55. So, I think the Yonex Ultimum RQ 1500 (OS), or, Dunlop 300G OS should do the trick. What do you say? Please give me feedback on these 2 rackets. Thanks.
