Flat Roof...TPO or Dura-Last

I was planning on using white TPO but was introduced to the Dura-Last. Everything I read leads me to believe Dura-Last may be the way to go...

Your thoughts?

Does this mean YOU were going to install it, or just want to know which contractor to deal with? I doubt that there is much difference, IF ANY, between the two. The key component is a proper installation technique.

I already have a commercial contractor that does residential for each material. I agree with the proper installation...thanks.
