I have got the confirmation from Yonex that the rackets are same , and the only change is from aesthetic point of view! check if its genuine
It's genuine. That's the first thing that I checked. Funny. It feels more to the 3ug5 z force 2 than 4ug5 (I have both). No problems. Plays well. Probably I got the heavier end of 4u range.
My rudimentary 2 cents would be using a scale and measure the weight (frame with grip and plastic) regardless of BP and what not before buying. Over the weekend I had the chance to weigh a few Duora10's and a 90g 3ug5 one felt much more intense than a 88g one, which felt so light and agile. Naturally my friend took the 88g one since he had one which had the same unstrung stock weight. Thus, if you are planning to get more than 1 piece of the same thing, I would suggest a scale and fix a number and stick to it. You should get similar feel. My ideal 3u dry unstrung weight would be 88g.
