the grey cymbals are part of the sdx set up and have "zone intelligence" basically you can set a ride to have bell and edge middle sticling and depending on location it will play and mix the sounds
of coruse it does not need to be a cymbal sample the also swing on the stands as would a normal cymbal and that helps to break up the rather monotonal cymbal strikes you might get
if you've played the rolands you'll get the idea
the hexapyramidals they were rare then and more so now 
i've seen two on ebay in the past year 
basically i belive it's a two channel trigger bell and rim and was in the sds v era so nice and hard on the hands
the ones i've seen were white or black and sold for around £50 each
