I use .029 for hunting. For target I think .019 or .010 would be better.

I used to have .29's but switched to .19's. I like them much better. They are more fragile but I've only broke one and that's because I was jacking with it. I like the smaller pins better. I would probably even prefer the .10's. That's for me, anyway.

.019 for 20 yard and .010 for 30, 40, 50, and 60

I agree with TFOX, I use .029.
