I had a chance to play with the "new" Donnay Pro One 18x20 for the last week and hope this review is helpful. First of all, I am a 4.0-4.5 level player. I currently am using the Youtek IG Prestige MP, previously I used Babolat Pure Drives. Only customization so far is an overgrip and rubberband vibration dampener and strung with a Donnay Syn Gut at 55 lbs. I will compare it to the Prestige throughout. Groundstrokes: My game is built around my long, fluid, and flat groundstrokes; I play aggressive tennis and always look to step into the court to end the point. My favorite part of the P1 was hitting groundies. The frame itself felt very solid upon impact, but also provided some nice ball pocketing flex. Swingweight felt good, but at times when I wasn't in position the racket did feel a little sluggish getting through the ball. The good thing is, this frame has a huge sweetspot and excellent stability. Off center shots didn't seemed to phase me as much, and I seemed to consistantly get that nice sought after "thwak" sound when connecting with the ball. Additionally, I noticed a lot of spin potential. Although I don't hit with a lot of spin, I did see that I could generate quite a bit of action on the ball especially considering the 18x20 string pattern. Comparison: I would need more time to decide which I like better for groundstrokes. It's hard to beat the Prestige's precision, but I did feel like the P1 was more forgiving off the ground, and definitely offered more spin potential. Also, it handled off center shots better than my Head does. I was consistantly hitting deeper with the P1, although I did feel more comfortable swinging out completely (no matter my position on court) with the Prestige, whereas I had to be slightly weary to not overhit some shots with the P1. Volleys: My volleys are pretty solid. I wouldn't say they are my go-to shot, but if I need to hit one I am comfortable doing so to end a point. The P1 actually surprised me on this part of the game. I expected it to be not so manueverable... as I did find it a bit sluggish on out of position groundstrokes. However, the stability of this frame really impressed me and made up for the less than manueverable feeling. It allowed me to absorb the pace of the incoming shot and redirect it without feeling any "fluttering effect." Comparison: Again, I would need to further test these two frames against eachother to determine which volleys better. As of right now, I would have to go with the Prestige, as I still think it is my favorite volleying stick because of the manueverability factor and accuracy off the string bed. It feels like more of a scalpel at the net than the P1. Serves: Serving was a thrill with the P1. It's not the heaviest stick out there, but the plow through and stability really impressed me. I was thumping serves into the court consistantly and found the large sweetspot helped generate nice kick and slice when I needed it to. I really had to have a fluid motion, however, and let the mass of the stick drive through the ball. Additionally, when I went for extra zip and power, it was available. Comparison: P1 wins hands down. I served well with my Prestige at the beginning, but now find it difficult to generate pace and power without arming my motion too much. The P1 gave me extra power for less effort, which is perfect for me since I can be guilty of arming the ball during my service motion. I will note however, that the Prestige does have better accuracy, and I was able to hit my spots better with it. Here's hoping that the P1 can improve on that area as I play with it more. Overall: Overall I can say I was really impressed with the Donnay Pro One 18x20. It really shines on all areas of the court. It's stable, has a good mass, feel, and offers a nice power:control ratio. I did get a chance to test the 16x19 version, and found it felt stiff, had too much pop and I couldn't harness it's power. This new 18x20 version is much improved, with greater control and flexibility. I would compare it to the Wilson nblade 98 and obviously the Head Youtek Prestige MP. Definitely worth a try, IMO. I'll try to answer any questions you may have to the best of my ability! Here are some pictures first with the prototype "X-Dual Pro" and then a headsize comparison with the Prestige.
