Bam best post yet very helpful thanks. Ive been shooting and the pins actually pretty much cover the bullseye on me. I am not sure what size they are but I am going to check on some smaller ones now.

All depends on the range you'll be shooting.
For 3D....at 40 yds.....029 would cover too much of my target. I have .019 pins for 20 and 30 yds..... .010 for 40, 50, 60.
If I was only using it for hunting.....20 and 30 yds.....I owuldn't be afraid of .029.
