Update. I now (temporarily) have both the pilot pad and the co-pilot pad. I already had the pilot pad for an Abyss headband modification, and wanted to see if the co-pilot pad would be better for that. It is not. I will continue to use the pilot pad with the Abyss, at least until I have tried the new Abyss headband.
I do not have any comfort issues with the VC, and therefore I will not be using either of the pads with it. With the VC, I think the pads take away from the looks, while solving a non-existing problem (for me).
But for those who are considering these, I just tried to fit them onto the VC. My observations. First of all, you really have to remove the leather strap. Second, both will fit, but both require some pulling and squeezing to get it right. The co-pilot might fit a little better due to its width, but the difference in ease of application is smaller than I had thought. The co-pilot pad looks a lot wider, but actually, the area where the headband will fit, either between the velcro strips (co-pilot) or next to it (pilot), is not that much wider. The main difference is that the co-pilot pad has strips on both sides, which allows for a more centered headband.
The final difference is the padding. For me, the pilot pad wins easily here. While the co-pilot pad has two areas/nuggets that are thicker, the
entire underside of the pilot pad is considerably thicker than those nuggets, more cushiony. The co-pilot pad has almost more padding on its top-side (where it is not needed). I guess you could reverse it, but then you would have two mini horns on your head ..
I hope this helps. I think can both be very useful products, whereby the pilot pad has superior padding and would therefore be my pick, unless you a) have a very wide headband you need to fit it around, or b) you care a lot about the centered positioning of the headband.
(In the end, I will not be needing the co-pilot pad, and my dealer has kindly agreed to take it back.)
