One of my dogs chewed up a set of plastic/rubber friction pads that I had taken off to make some adjustments to one of our BP/Ws....I kept forgetting to order replacements and so we just kept diving with the cam straps without them. We have not experienced any issues not having them, and not having them makes it much less of a hassle and quicker to thread the cam straps through the slots in a plate and wing.
YMMV.
