I'm a long time XIOM rubber player and use XIOM Vega Pro and Vega Japan rubbers. With the new Omega V series coming out, I had to opportunity to "test drive" an Omega V Tour.
Omega V Tour is the same sponge hardness as Vega Pro or Omega V Pro, but with a topsheet that uses a differen pimple geometrie. Pimples are a bit wider and more dense. The topsheet therefore feels more dense and compact, compared to a Vega Pro.
I played the Omega V Tour on the FH in 2.0mm (on an Adidas Fibertec Classic), keeping my Vega Pro 2.0mm on the backhand for comparison
As all XIOM rubbers is takes a couple of hours until the rubber reaches its normal characteristics (XIOM rubbers feel stiffer and harder than their really are in the first 6 hours of play, so don't be surprised).
The Omega Tour has more catapult than the Vega Pro, while maintaining the same spin. The catapult effect kicks in very late, but then is higher than with other rubbers I played before.
Short game is easy and opening loops agains backspin aren't a problem. However playing loop against block or loop becomes a challange with the OMEGA V Tour. The additional catapult of the Tour made it difficult for me to not overshoot. On the otherhand, when not playing fast and strong enough the ball would drop into the net.
The OMEGA Tour is quite delicate to play, because the window for the right amount of force and speed to hit the balls is very narrow.
Push and Short game: Easy and very spinny
Block: passive blocks are easier, active blocks are a challange (catapult effect)
Loop: on backspin OK, against block or loop to difficult for me
Drive: challenging as well, because of the catapult effect
XIOM OMEGA V Tour is an excellent rubber, with long durability (played for 3 month, without any noticable degredation), but way to advanced for me. The number of unforced errors was too huge and therefore I switched back to Vega Pro.
