I received these 4 frames from TW to demo yesterday. A buddy of mine, who is looking for a ProStaff 95 replacement candidate, had called me to hit. We went out and hit for a couple of hours yesterday afternoon. The order of finish for me was: 1. Dunlop AG 100 2. Yonex RQis 1 Tour Light 3. Dunlop AG 500 4. Head Radical Pro MP The order of finish for my bud was: 1. Yonex RQis 1 Tour Light 5. Dunlop AG 100 6. Head Radical Pro MP 7. Dunlop AG 500 I'll have to quickly add that these 4 frames are all really nice. The Head finished last, but it wasn't by much. The AG100...well it's just sweet. The numbers for my buddy aren't a mistype. He liked the Yonex that much. Dunlop AG100 I spent the majority of my time with this frame. I haven't hit with any frame which sounds/feels so much like a frame from my youth. This is probably the only new frame I've hit with in the last several years which felt right in my hand on everything to start. It came strung with a Dunlop string, M-Fil Tour 16 which was heavily knotched and broke toward the end of our hit. I suspect it was strung from Dunlop and further surmise that it was strung at 60 which is midpoint; further proof was that it was stenciled. I restrung it with a multi at 58 and will play with it today and tomorrow. Things didn't start out well, the first groundie I hit was a framer and the first 3 volleys were in the net. But, after that, it was a really really nice hit. Groundstrokes Off the ground, this frame is very maneuverable. It is also a control oriented stick. Those who've commented that it is a spin machine aren't exaggerating. It again reminded me of wood. The kind of topspin this racket produces is very easy to get and plentiful. Slices are likewise easy. Several have commented that the frame could use some weight. I disagree. The frame weighed, strung, exactly what TW has on their website, 332 grams. I found it be be very well balanced and rock solid off the ground. As noted in another post, I'm looking for something lighter than the 12.7 ounces I'm swinging now as playing 2+ hours in the heat/humidity of regionals proved to be a little taxing. My preferred groundstroke is the backhand. This frame lined up really well on that side and I was able to come over and under the ball with equal proficiency. Forehands were easy to hit as well. I never felt late or rushed with the frame off the ground and always had a great feel when hitting the ball. Off center hit weren't jarring or tinny at all. They again just felt solid. Volleys Volleys have nice pace and direction is easy to get. Touch volleys were also a pleasure with this frame an I found it very user friendly around the net. The frame is a natural at net and doesn't play like a 90. I took volleys from the service line forward and found that I could get great depth and direction with the AG100. The frame again is way more maneuverable than what I've been playing with and I never had a problem getting the frame into position. Serves Many have commented that this is where the AG100 shines. Far be it from me to disagree. I served some with this frame and we played out the point crosscourt. Serves had great direction, spin, and pace. What more can you ask for? Coming in behind them proved to not be a challenge as the frame volleys like a dream. Returns Returns were a little different with this frame. I blocked most of them back, but that may have been more due to the serves I was seeing. Again, they were solid and well directed. This may be the one area where I need some time with the frame. All in all, a real winner. The only downside to this frame for me was the grip. The stock grip is just plain slippery. I put a Tournagrip on it and problem solved. If I continue to love this frame, I see leather on it. Yonex RQis1 Tour Light My buddy was enamored with this frame. I thought it had the best flex/feel of any Yonex I'd ever hit with. It just felt right. Groundstrokes This frame was great off both sides on the ground. It felt like it was too light, but every ball I hit with it had plenty of stability and moved through the ball well. My hitting partner was reticent to let me hit with this frame. He was generating great topspin with it and lauded the control of this frame. Volleys I have always loved Yonex frames at net and this one didn't disappoint. It was very maneuverable and volleys were crisp and well placed. My hitting partner isn't as much at home at the net, but he really liked the way this frame felt at net too. Serves I didn't serve with this frame, but he did. He hit some great serves with good direction and spin. I didn't see a drop off between his current frame and this one at all. Dunlop AG500 Tour I got this frame because it didn't fit what my perception of a good frame is. I've found that doing this often results in a nice surprise. It did here as well. This frame doesn't seem like a frame a 4.5 would like, but it is. It did everything well, the only thing it didn't have was the feel and sound that the AG100 did. Overall, I didn't spend much time with this frame, but I think I could play with it pretty easy. It's nice to know you have options. Head Radical Pro MP This is a really nice frame as well. The major drawback to this frame and the reason it finished a close 4th is the grip. I ordered all 3/8, but this one felt like a dang 1/4! Had the grip been a little more to my liking, I think the frame would definitely finished 2nd or 3rd. It has great flex and feel. Around the net it was very maneuverable and volleys were a pleasure. I just couldn't get comfortable with the grip size. I'm playing once today and twice tomorrow with the AG100. I'll post a follow up then.
