It depends on if the pad is actually coarse, or stiff. My favorite cutting pad for that past couple years has been the green hex logic, and recently, the Lake Country Cyan Hydrotech.
The pore structure of both pads is what seperates them. The green hex is an medium density open pore pad. I get great cutting, and coverage with this pad. The coverage comes from it's ability to conform comfortably to contours. Another pad with this characteristic is the Lake Country pink ccs. I would love to try a flat or ccs made out of their purple kompressor foam as the pores are even larger.
The Lake Country Cyan Hydrotech is a closed cell prepolymer foam. The pad itself doesn't add to the cutting as much as the abrasive in the compound. It primarily relies on resistance, and density of the foam to push the abrasives into the paint. These pads have the characteristic of leaving a really nice finish as well. With these pads, the pressure plays more of a role in the performance of the compound.
I don't know what company made the pads in the pic, so I can't comment on them.
