For HUNTING there is no nead for anything smaller than .029. You just increase the odds of damage and not seeing them in low light if you use the .019.The whole reason we have the craze of bright pins is so we can see the .019 in a hunting situation BUT when the pins are that bright,they create a halo effect and are even harder to be pin point accurate with.My pins are not overly bright but I can see them on a tree well after legal shooting time.I am comfortable out to 50+ yards with them in a hunting situation.
Check out the outdoor target rigs,they do not have the overly bright pins on them.Most will use a small blue light that will shine on them in an extreme case where they can't be seen.I NEVER needed a light outdoors with my .019 pins.(but I wasn't hunting at dusk)I did use one indoor.If I were to get back into competition,I would probably use the .010 pins,the smaller the better for targets but not needed in a hunting situation IMO.
I know this is 180 degrees of what most people are into today so take it for what it is worth.
