I agree, I think that is the difference between black & grey. I don't think
there's significant difference in friction between "slotted" and "un-slotted"
black pins, but they do (both kinds) allow some rotation, just not as much as
the grey ones.
The point I was making was the tendency of the black pins to become very
difficult to remove if left in place for an extended period. I'm not sure why
this is, it may be they just distort or expand over time.
