My 105 5.6 and 65 f4 are both rodagons. I also have a 50 Durst Neonon, 63 2.8 Nikkor and various others. Only two lenses lag behind and they are the two newest and cleanest: the 80 f4 Rodagon (which only really shows up weaknesses with 35mm negs) and the Schneider 50 Componon-S. The 105 Rodagon produces 35mm prints as sharps as from a dedicated 35mm enlarging lens.
