I've got a vortex viper spotting scope. Was looking to upgrade to the razor. A buddy has a Leupold SX-5 that is really nice. Of course the razor & SX-5 will be 85mm objective. Who has went from either of the razor or Leaupold to the Kowa saw a huge difference. I need better clarity then the Viper gives for counting tines on moose and spotting impacts for long range shooting.
