How do you gap/split your pins? It's impossible unless you have your pins off to the side which is not good especially when picking a hair or another nock on a 3D range. Seems odd to have vertical alignment?
It's not hard at all to gap shoot. I don't even see the black of the pin between the fibers. As far as being able to see a nock between the pins, come on, what if the nock was at the exact distance of one of your pins, how do you not block out the nock then? Same thing, you line up the pin, over the nock, and shoot!! The nock/target is not visible in either case! No?? And I have never picked out a single hair of any target, seems to me that all the hairs are too close together to pick one single hair out, even at 20 yards!! Instead, I pick a spot, and shoot.
The vertical pins aren't for everyone, but gapping the pins has not been a problem for me, and many others.
Seeing between or through the pins is easier for some than others, just like some can see arrow flight, and some can't!! Odd as it may seem , I like the vertical pins better than my old horizontal, and it took a very short time of practice to get accustumed to the difference!
