Trying to decide between Leupold SX-1 Ventana 80mm or Celestron Ultima 80 or 100mm. I have a Konus Konuspot 80mm now and can't see holes in paper targets @ 200 yds unless conditions are favorable. I know even the best scopes have problems with heat mirage. Do you think one of these will at least be better than what I have now? If not, I will just have to keep saving up to get a Kowa or Vortex.
