I agree Rob and Muskyman, if your shots aren’t any farther then 30 to 35 yrds then shooting with a single pin will work because an arrow shoots reasonably flat at those yardages. We use too shoot 3-ds and i had a set of hoyt target pins that had a very small ball on the tip and we shot at alot of diffrent yardages and at diffrent decoys. Fox at 40 yrds up hill, bobcats at 10 yrds and deer everywhere in between and out to 50.
What i liked about the small tippped hoyt brass pins was that it was easy to move this small ball into place over your kill shot and over the whole decoy withut covering it up with the sight. When i first started shooting i had a set of sights that were bigger tipped and they covered the animal at farther yardages, i put on a set of small tipped pins and have never gone back.
I bought a bow from Tom Gursky here on the site and it came with a set of small tipped fibre optic sights and i was impressed with the small tip on the end of the pin. I shot this bow and with these new fine tipped optic sights im satisfied and see no need too change to anything else. A fine tipped pin is the sight for me.
I shot a 5 pin sight and had all pins sighted in from 10 yrds to 50 for 3-d shoots. We did quite a bit of driving to various shoots and i had my 50 yrd pin set dead nuts and could hit the kill zone on a bear, which is a 5″ circle and hit it most of the time at 50 yrds. I got use to using the pins and was confident at that yardage too.
If i had a shot at 50 that i know the arrow would get there befor he spooked i would be able to take it but it had to be the right shot for me to do that and my bow was set up to do that if the shot arose. My first consideration would be a fine tipped sight now matter how many i chose to shoot with. Shooting quite a bit at diffrent yardages and your eye comes to that tip almost automatically. The choice is strictly individual and what that person needs and wants to shoot at in all conditions.
