I've seen the videos and manual trim on the NG is just about impossible at higher speeds. But there is a subsequent procedure to unload the force on the stab to allow pilots to regain the ability to manually trim and allow some elevator authority (assuming sufficient altitude and trim isn't jammed). I agree with the last sentence, however. That change was not well thought out.
