300 miles on the C-17 Brooks Cambium (rubber) Saddle

When the rubber meets the road… of something like that?  At 300 miles the Brooks Cambium feels like it did at 12.  Which is good and bad in its way.  Right out of the box it felt like a leather brooks after several hundred miles; the leather gets better the more miles you put in.  So far the Rubber stays the same.
