I need to upgrade my spotting scope.

I would love to go with the Razor HD 20-60x85 but my budget won't handle it this year, so I was thinking of going with the Viper HD in 20-60x80. I could always sell the Viper HD on the forum next year and buy the Razor if I want to move up.

Two things I've heard:

1. The main difference is that the Razor is much easier on the eyes than the Viper and I will regret buying the Viper HD if I do much glassing.

2. Someone in their 50s like me probably won't be able to tell much difference between the two scopes in clarity and light transmission.

What do you think of the Viper HD spotter in 20-60x80?
