I have the Swarovskis in 8x30, 10x42, 15x56 and Leicas in 8x32, 8x42, 10x42. I also have a number of other premium grade binoculars in various sizes. I have always been something of an optics nut and have lots of premium spotting scopes and other fine optics. Still, the binoculars I reach for most of the time for hunting are my Swarovski 8x30 and my Leica 8x32 because they are the best compromise of performance, size and convenience. The bigger binoculars are nice under the right conditions, but I prefer not to lug them around when I don't need to, and I don't need them most of the time.
