I have never used a setup as was mentioned (round pin guard/ peep alignment with multiple pins) so take my opinion FWIW. I'm just trying to picture the geometry of the shot from the eye, peep, pin guard and field of view. I'm also trying to picture the form used and the basic "t" stance whichissomething to be sought after andduplicated whether the shot is 10 yards, 80 yards, downhill, or uphill.

Although the field of view would be limited as the pins get close to the upper limit or lower limit of the pin guard (could hamper seeing the target well) in not centering with the peep, I would think that there would be an inconsistancy in phsyical form if the upper and lower (not centered) pin were brought to the center of the peep for aiming whether that be from dropping or raising the bow bow arm.

Not to say that there maybe a tendency to center the aiming pin.
