My first racquet was a 6.1 95. In a years time frame I ended up doing a full circle from Head, to Yonex, to Babolat, and now back to my 6.1 95. I play my best tennis with the 6.1 even though I tried to convince myself a better racquet for me was out there. I think you should stick with the radicals. I can't speak for the youtek, but the microgel Radical MP is a great racquet and is only 90 dollars. I have been playing with it for two weeks and i've been playing the best tennis of my life. I'm beating people I've never beaten before. I do think you need to add some weight to it. I'm sure most of it is psychological, but I've never been able to consistently take huge whacks at the ball and keep in in play. Who knows, I'll probably be back to the 6.1 in a month.
