Greetings. I just installed a new Viper Predator Pro MT sight on my bow. I looked through a bunch of information and read the forums to get an idea on whats out there. Rob gave this sight a stellar endorsement and I talked with him and decided to take the plunge. I am totally happy with this purchase. I will post a photo of how well I shot with it first time out. My question is what is the significance of the 3rd axis in regards to a bowsight. Obviously everyone is familiar with the standard 2 axis set-up with elevation and windage but what role does the forward/aft axis of the whole sight window play? I know that is something competitive shooters are very familiar with and I was just curious to know what advantages/disadvantages there are when it comes to hunting. If anyone cares to try to explain this in more detail, it would be greatly appreciated as always. Thanks!

Here is some visual proof of how well I can shoot using this sight, this happened on my 3rd group at 20 yds. I have never done this before so obviously it must be the sight right?? The funny thing is I was using some Easton Axis 400 arrows, I would have never thought you could robin hood those skinny things.
