First off, gotta say, I absolutely love the mod, and especially the cargo pipes. They look like barrels, and I'm -definitely- going to use them that way at some point. Will share pictures here to show off the mod some!

Currently you have the small-block Conveyor Pipe Cargo Small balanced with the small-block Cargo Container. The large-block Conveyor Pipe Cargo Large costs the same as a small-grid Large Cargo Container, when a large-grid Small Cargo Container costs considerably more than that.

Could you change the large-grid versions of these conveyors to use the large-grid storage costs? Perhaps you could use the same model to create a small-grid "large" version, too.
