I have just gotten two of the O3 Tours that are different in their markings. I have one that has a swingweight of 290 on it and it says at the top of the racket "Midplus+" and then I got another one that says the swingweight is 295 with the word "Midsize" at the top of the frame. It would be interesting to see what your racket says in those areas to compare for those of you who have this frame. They seem identical for the most part, but I haven't weighed them or looked for any other differences. I thought I would start on here and see if they are just a different batch. Thanks for any input in advance.
