The comfort of the suede strap is like none other, luxury! However, the bit of cushion can cause a tight fit when being used with a Co-Pilot pad. Thus, I might prefer the lambskin strap when being used with a Co-Pilot pad, which provides enough cushion and weight distribution for me. I can’t speak to use with the Pilot.
I just received the Be2 lambskin pads. The quality of the leather seems to be more premium (including thicker) than the Auteur, Universe, and Eikon lambskin pads. What I didn’t previously realize is that the Be2’s foam/fabric section that covers the driver is noticeable thicker than all the other pads I’ve tried. Maybe that partly influences how the Be2 pads are brighter than the other pads (Verite pads may have the same feature, but I don’t have direct experience). Setting aside sonics, I personally prefer the minimum amount of material between ear and driver.
