I have been using the 7424 for a few years, not that much, maybe twice a year, and have not really experimented. I have been using the 6" counterweight with a 5" yellow hook'n loop backing plate and a 6.5" pad. After doing a little reading I am wondering if that is a good setup. Should I switch to a 6" backing plate? Or go down to a 6" pad? I don't feel like buying all of the above and experimenting. What do you guys recommend?
