Seeking advice on the Internet for certain issues makes good sense. Seeking advice on proper tubing selection for your custom frame is not one of them.
This is, of course, entirely my opinion and yours may differ.
I strongly disagree with this. Everyone should be educated when talking to a builder and if they shy away from questions about tube selection, or suggest options different than what your research shows is appropriate, you should question them and expect answers until all the pieces come together. Don't be a sheep bowing down to the framebuilder god. Knowledge is power.
