Much more so than a felt. So then when your cymbal and the pad rotate while playing, the cymbal gets angled in all kinds of weird directions. It was pretty disastrous.
I've found this to be true as well. To me it also seems the cympads enable the cymbal to spin around more easily than with regular felts, and it's bloody irritating. The cympads are okay as a top "felt", but even so, I find myself preferring normal felts.
