So I was sitting there thinking about this and I think I should decide now if I want to do the engineers. If I do then I should whistle for my Krait now to this station. Fee is 98 million, 43 hours. By the time I reach Colonia it will have already made it most of the way if not arrived. Once there, call for the much shorter transfer. That makes sense and will save a couple days of waiting. In all, the cost of transferring the Krait both ways will be about exactly what I've turned in for data, so I'd at least be breaking even already
