Study the book “Namaz-e-Ahnaf” authored by Mufti Habibur Rahman Qasmi Allahabadi (Urdu) and “Fatawa Shami” etc (Arabic) books. You shall learn the correct method. Hanafi Fiqh is not any other way than the way of the holy Prophet Muhammad (صلى الله عليه وسلم). Being a Hanafi, why do you ask whether the Hanafi Fiqh was more important or the way of the holy Prophet Muhammad (صلى الله عليه وسلم). It seems that you are misguided by some Ghair Muqallid. It is sunnah to raise hands at the time of takbir-e-tahrima according to all Imams. But hands should not be raised at the time of bowing for ruku before sajdah. Leaving rafa yadain is proved from the holy Prophet Muhammad (صلى الله عليه وسلم) which Imam Abu Hanifa and many other Imams (رحمهم الله) have adopted. The hadiths of rafa yadain are not preferable.
