Just purchased a PC. I also purchased some propel pads from Excel. I'm still a touch confused about which pads to use and at what speed. I have some PB SSR 2.5, 2 and 1 and some VM. I figured the VM would be blue pad at 5. Would the SSR 2.5 and/or 2 be used with a green pad? What speed? As for the SSR1 would that be a product I would use with a blue pad? Again, I'm unsure of the speed to use. Any advice would be appreciated.
