Bryce Speed and Speed FX

Hi, Alois

I just wanted to know that which rubber is better bryce speed or bryce speed fx.  i tred to find the difference but it says that everything is same but bryce speed fx's density is lesser than bryce speed.  what does density do?

Thankyou

Hi Zohaib,

From what I know Bryce Speed FX is a little faster with a tackier surface for more spin.

Anyone else out there able to help Zohaib.
