Me interface with GeoStrata stones in the export positions. Use an unpowered itemduct set to red arrow (extract) and right click crescent hammer the interface until the mini arrow points at the itemduct attached side. Repeat with as many ME interfaces as you need. Precision export buses would work as well. Fuzzy export buses would work with just one of the geostrata stones of each type (cobble, smooth, marble, etc) in the ghost slots.
You can either place every type in the ghost slots of a precision bus or interface, or you can exploit the shared item IDs with a fuzzy bus and one of each type.
