Okay, thank you for sharing your thinking.Their comment reads:
They (1.) experience the upgrade as "crazy" and "big" and (2.) talk about merging the budget of two binoculars to get one. Which tells me they expect the one binocular to be the "crazy" and "big" upgrade and potentially even carry the performance or value-contribution of two binoculars (hence merging the budget). This expectation may prove to be true or may not be true.
For the record, my own personal experience of high-end glass is limited to SW Habicht GA and my entry level hands-on experience includes celestron skymaster, kowa b2, and oberwerk deluxe. I was just articulating the thought structures as I saw them to help in making a choice.
