Vertical pins in the first 20 minutes and last 20 minutes of hunting hours are misserable IMO. Not enough light to illuminate the pins....looks like one big black vertical line.

With horizontal pins, you can see above, below and to one side of the pin.

With vertical pins, you can see left side and right side. Not above, not below.

When I am hunting, I need to know where that bottomchest line is of a whitetail. I pick my spot approx 6" above thatchest line and let er rip. With additional pins in the way....I can't see that line very well. Quite annoying.

I bought a Matrix sight and it's not going to work for me. I anchor high, with the loop at the corner of my mouth like a traditional shooter. This type of high anchor causes my sight to be set lower on the bow than most people. The Matrix, due to the design, has a lot of extra thickness, levers, and sight materialat the bottom of the sight. Iam shooting Blazers, cock fletch up, and the Blazer (to my eye) looked like it would contact the levers, or sight material on the Matrix. On a sight with a smaller housing, like Tru Glow, I don't have a problem. I am settingmy sight so that I can align the sight housing with / inside my peep's field of view as an aiming reference.
