serves: Paired with good rubbers you can easily get a lot of spin onto the ball. Short serves are very easy as the blade is not too fast. Even serves that require better timing like the reverse pendulum are easier due to the long dwell time.
receives: Just as expected from an allwood blade,the infinity performs very well in the short game. The dwell time and the good feeling of the wood help play short pushes as well as flips with forehand and backhand. Pushes and any kinds of crazy receives are easier with this blade.
open ups: The dwell time really helps on playing heavy spin topspins. You have a lot of time to generate spin and go for a good placement on the table.
topspin: The follow up topspin also works perfectly fine.
Speed: The general speed is not as high as let's say a viscaria's, but still fast. If you are physically fit, you'll have no problem blasting the ball past your opponent after opening up with heavy spin.
countertopspin: Countertopspins also work well, but require proper technique and timing.
conclusion: The infinity is a very good allwood blade that really has no weakness. You can open up with a lot of spin and follow up with a well played loop and then a kill shot. Especially for forehand oriented players this blade is fitting. Backhands are easier to play because of the increased dwell that gives the blade more control. If you're looking for an offensive blade that can play all gears ranging from slow and spinny to fast, then this is your blade. If you're using a carbon blade but struggle with service receive, then this blade is for you. If you have enough physical strength but your receive game or open ups are slacking, then switch to this blade.
