I think people listen to certain podcasts by people who hunt and spend time afield behind glass way more days and weeks than the average guy like me. You hear about their successes and see their instagram page filled with trophies and think "they use alpha glass, and if I do too that could be me with all those animals." Chances are, the difference between a pair of Mavens and a pair of Swarovskis will not be the deciding factor between you punching a tag or not, for 95% of hunts. If you can afford Pures then why not? If you can't and have to settle on a pair of Mavens you'll more than likely be just fine if you dedicate yourself to hunting as hard as you should be.
