There is another mistake. I get opposition every time I say it, but the Propel orange pad is MORE aggressive than the yellow.
Save your arguments...I will post the response I got from Patrick on this topic:
Orange vs. yellow

"Make no mistake, the orange is more aggressive. The reason for what others are saying that the orange may not be as aggressive is simple. It IS more dense, its stiffer, different composition. Being as it's stiffer, total surface contact & pressures may actually be less than other pads. Imagine a real stiff pillow, you lay you head on it and your head just kind of rests, it doesn't sink in to the pillow. Take a soft pillow, rest your head and you sink it.
Well the same goes with the reticulated German foam. The softer foams will conform to shapes, total surface contact. When you get to the stiffer foams, they rely on pressures applied, and with the PC, theres only so much pressure you can apply before the machine will slow down. One trick I have learned with the Propel Orange, being as its is so stiff, is you can still reep the benefits of the density, if you attempt to soften the foam. I saturate mine in water before using, spin dry, and use, this alows for better conformity and evens out the pressure somewhat. Kind of like a dried sponge? You get it wet, and it conforms easier."
