Honestly I don't know if it's worth selling the razor until you are ready to upgrade to top of the line glass. I have used an Athlon ares 65 for the last 5 years and though it's not the best optic it has served it's purpose. I bought a kowa 773 this last year and that will be my do it all scope now but I only had one experience with the athlon that I felt like the kowa would have showed more detail to make it worth the money. I have used meopta meostar 10x42's and my Athlon spotter hunting with my buddies that own only Swarovski binos and spotters and they didn't see anything that I couldnt see with my set up that cost 1/3 of the price.
In my opinion binos are the most important piece to the puzzle like was mentioned earlier
