I just went thru this a few months ago. After checking around, comparing, and lamenting, I ultimately settled on a pair of Swarovski 10x SLC. The SLC is heavier than the EL, but the glass is now the same. Lieca was a close second, and Ziess was a distant third as their quality seems to have deminished in the later models. That is my choice for guiding both archery and rifle hunts out west.
