What is your BTX glassing setup?

[Fowl Play]

Already planning for next year where I am going to cash in my elk and deer points on some hunts above treeline. Was able to scout out the location this year and found some good glassing spots that are within 1.5 miles of the truck or trail. Can easily glass some huge country between 1-3miles. Seems like the BTX will be perfect for combing that country to spot animals, but at the longer ranges that fixed 30-35x zoom may prove problematic for judging animals. You guys who use the BTX, what are you doing in this case? Are you packing an extender or a spotter eyepiece and swapping it in the field to judge? Is digiscoping enough to zoom in to judge an animal at that distance (even if blurry?). Also would be interested in what tripod setup you guys are using for say a BTX with 115mm.
