Ritchey-chretien Truss or Tube?

Hi there,

I'm considering of purchasing 10" (ten inch) Ritchey-chretien scope and have an option of having it in carbon tube or carbon truss. Later being a little more expensive. Which one I should go with an why? Cost is not a factor since the difference is not that big. If you have any additional questions to help you give better advise please ask. It is a lot of money and I want to make better choice out of the two.

Please help. Thank you!

If thermal isolation isolation is more important, go Truss. If stray light isolation is more important, then go with a tube.
