Traveller IW or Spaceships Rules?

[JMason]

So, I've gotten a bit burned out on my current campaign (very DF-ish) and have started flipping through IW again. I think my next campaign will be the "default" IW Terran Free-Traders game (I went a bit wild with my last IW game).

But I'm wondering if I should use the rules in IW for spaceships. Design, Combat, etc.

I know that Spaceships simplified the design a bit... does this make the example ships in IW unusable? Also, isn't there a new combat system in the Spaceship book(s)? Is it more detailed, less, easier to run, or not?

Has anyone here has experience with the two sets of rules, and what do the recommend?

PS. I'm pretty sure this has been discussed before, but it looks like the threads are gone. Sorry if I'm asking folks to repeat themselves.
