When someone is in the process of conversion and saying blessings to practice, should he say the actual name of Hashem or “Baruch atah Hashem, Elokeinu...” During the Amidah or other prayers, also as practice, is one allowed/recommended to say “G-d of our/my fathers” or is it disrespectful since my parents are idolaters?
