I don't know how well that pad is going to work on your PC7424XP or GG 6", plus you will need a backing plate for the 3" pads. I actually use the 3" MF on a GG 3", but it's a pretty wimpy machine. You can get a 4" backing plate and another brand of MF pads in ~4" size, and do that for the pillars, a 4" setup is great for your PC for spot correction or tight places.
