I stepped up to the 6" backing plate after using a 5" (with 6.5 pads) because I found that the pads would concave down in the center and flare up on the outside, after awhile when working with pressure on the edge it was able to pull itself off the velcro.

Haven't had any problems with the 6" backing plate so far, plus now I feel like the pad is supported better, no more "bowing up"
