I used an OL5000 on my Bowtech Tribute for awhile. The sight is a very nice sight. Strong and durable. Once you get use to the slider sights you won't want to go back to the multi pin sights. I set mine dead on at 25 yards. Then I practiced at various distances to know the hold over/under. I got very good at it! Shot a couple good 3d scores that way last summer. First time I'd shot 3d in a looooooong time. I believe this is the best hunting sight because there is no confusing which pin to use. Accurately judge your distance and you have meat in the freezer!
That being said. I am switching to a multi pin sight. Not because they are better sights, but to use a slider in 3d you are forced to the open classes. They stretch the yardage markers out in that class. Hunter classes have to use fixed pin sights.
I plan on doing alot more 3d this spring and summer. Probably leave the fixed pins on for hunting seeing that I won't be as practiced with the slider
