I guess we just had to spin it the right way to catch your interest. :)

That said, the Spaceships series is good for roughing out designs; it's not so good when you want to get into the weeds (e.g., different kinds of spin gravity; the benefits that magsails have over lightsails; fine-tuned tonnages; and so on.)
