Which do you use and why?

I use a .019" 5 pin Spot-Hogg Hunter Hogg-It. I prefer the smaller aiming dots for longer ranges. I will admit for hunting purposes though, I would opt for a larger .029" if my sight didn't have the Hogg-wrap fibers on 'em. I want the brightest pin I can get when it comes to slippin' shots at whitetails during primetime.

I actually shoot a 029 for my close pin, and 019 for the other 3.

.029 4 pin extreme

Me too.

On the new bow I am shooting an Apex Atomic 4 pin with .019 pins. There is a light built into the sight so they are plenty bright in low light and the .019 pins aren't overkill in bright light.

I have a 3 pin .029 signt.

.019 and loving it.

Steroids are bad, ummmkay? If you do steroids your bad, ummmkay?

X2. I like to have as much light gathering ability as possible while maximizing accuracy at close ranges and having the ability to really pick a small spot at further ranges. The smaller pins are generally used only for 3d and practice, but it's nice to havethem.
