I use my 85mm 4+ pound scope for all my hunts that require a spotting scope. 1-2 extra pounds in spotting scope saves me a LOT of walking......granted sometimes it causes a LOT of walking too cause I see a bruiser of an animal way further away than I would have with a 50mm spotter. But nice to have options. Would like to pick up a Vortex 65mm for some hunts when the 85mm 20-75X Zeiss isn't required but still would like to get a good look at things.
Luke-Get a Diascope 65mm FL and use the eye piece between your spotters.
If I did that than I am afraid my 85 mm would become obsolete . As 56x and a 65mm scope would be tough to beat.
