I'm just waiting to see some time trials run in the ship, specifically undocking from a station, jumping, and landing on a planet. If it's enough of a slug moving in realspace, it may add enough time to each trip that the number of trips it saves isn't all that effective. The Cutter isn't that much faster per trip than the Type 9, but when I run one of each on two accounts, the Cutter always has a significantly larger contribution to construction than the Type 9 does, while delivering 70 less per trip with the setup I use.
