We used a new machine to make the current batch of pads and specified a smaller bevel. The only true difference is the bevel (amount of radius) on the front edge. Function wise, they work the same (same foam, thickness, etc.).

As you may have noticed, I have the SFX pads on sale. This is to make room for the next generation of SFX pads. The 3rd generation pads have a full radius on both the front and the back. The back side has the Velcro cut back away from the edge to add a margin of safety. The foams, thickness and, Velcro and Velcro attachment have not changed.
