Sorry if this is covered somewhere else, tried searching for something conclusive. I have a swarovski booster and I am looking to pick up my first pair of swaro binos. I want 10x42 and want to be compatible with my booster. I'm willing to spend 1500-1700 but if I could stay closer to 1000 that would be great. Which version do you all recommend to get the most bang for the buck, slc/el? Which generation? Thanks a lot for any feedback.
