I have the trophy ridge, what attracted me to it was it's amazing light gathering ability, I to found that the sight crawls vertically about every 25 shots. But I like the sight so much I'm willing to live with that. With the wing nut design it adjusts quickly to original position. My original reason for buying it was to be able to shoot in low light conditions, and I can now do that. Being mostly an elk hunter I was concerned like BIG BULLS as to the fragilness of the pins, I to hunt only on the ground, but I'am very careful around brush and branches, I usually hunt 20 days of the bow season and cover 6 to 12 miles a day all on the ground, and so far so good. BIG BULLS I'm keeping my fingers crossed. elknu1
