Quick review after 4 hours of doubles: The rok was playing like my Ozone tour.
More spin (nothing out of this world, but hey, it's a rok - if it were my ozone tour I'd probably be nadal by now)
More power, but in a controlable way
Big increase in sweetspot and dwell time. That's what I was looking for and I got it. Happy.
I was volleying very well during warm ups, very effortlesly. During matches, however, and especially as I got more tired, I felt I could'nt finish points well. I wasn't feeling confident to put away those balls or to confidently distinguish a lob from a drop shot. Never thought I'd say that, but I missed the crispness of my Ozone. Maybe I should have gone with a stiffer string to sart with. Very very comfortable, though, and might work really well for me on singles, but not so much on doubles.
Now the reason why it didn't work for me, in the end: it SUCKED on serves. No power, spin, nothing. I rely a lot on my serve, and I had a terrible time adjusting to the feel and lack of power. Many double faults and I was pushing it with zero confidence as my flat, slice and kick attempts failed over and over again. Felt really dead. Never got a great felling serve with this ELT. The rok isn't my favourite racquyet to serve anyway, but I don't think I'll try on my Ozone.
All in all, I have an easier to play with racquet, wich was my goal. But serving really sucked, and that's a huge part of my game.
