I like the 20-70 zoom personally. If i used it for "glassing" I would probably go for the 20-60WA, but for a quick look to try and decide whether the buck is 95" or 105", it is hard to beat the 70x. also takes great digiscoping photos. I sold my zeiss 15-45x65, which was a great spotter but I much prefer the meopta, although it is pretty big and heavy.
