I have PC and a Cyclo, the Cyclo is my go to machine. It seems the MF pads work better with some machines thank others. Has anyone tried the Optimum Micro Fiber pads/Hyper polish spray, with a Cyclo Polisher? For DA, it appears OPT only offers backing plates in 5". What did you use for the backing plate? I was thinking the Cyclo Pro-Guards might work. Thanks in advance.
