saddlepants,
You might want to check out the Cobra line of sights. I have a Cobra Sidewinder that has 5 pins and a large multi-color spool of fiber optic that has a cover over the spool. The cover gets removed at low light to allow the pins to glow. Thing is, I added a sight light, because there are lighting conditions that don't offer enough light for the pins to glow...one situation is a groundblind and another is being in a tree with a large canopy of leaves that won't allow enough light.
Also, keep in mind that a vertical stack of sight pins...or even a single vertical sight pin, can cause the archery to drop their bow arm to see the arrow in flight. Being used to horizontal pins, after the arrow is released, it's possible to see/follow the arrow's flight path. Using a vertical pin system can (not with everyone) cause an archery to drop their bow arm to catch sight of the arrow's flight.
Archery is full of personal choices and that's what attracts so many to it.
