Calibra lt and sound vs bryce speed

Hello,

Are the calibra lt and calibra lt sound faster than bryce speed? 

i'm currently using bryce speed (2.1mm) on both sides on my butterfly gergely 21 carbon blade and its working well for me

Also would it be a good idea to use the calibra or should i use a slower rubber such as boost tx in max thickness?

Hi Kelvin,

As usual I will let the experts comment of the different rubbers.

As far as the speed of the rubber, think about your level of your game.  Also if you are finding it hard to make short pushes and control the ball then the rubber is too fast.

You said that your current setup is working well for you.  Maybe you don't need to change at all.
