What are some of your nock heights and do you use 2 nock points? Im at 1/2" and use 2 nock points. The 2 nock points have made a huge difference for me.

Two and 5/8ths.

Same, two tie ons and around 5/8s some times a tad higher depending on the bow.

Two tie on nock sets, and 5/8" pretty typical. I use 5mm/.204" carbons with Easton X Nocks. There's definitely situations where a fuzz less or more are in order...

For years, I shot 3-under with a single nock point at 5/8"

When I started putting a second nock point under, they all seem to shoot better!! Quieter, too...

2 nock points and 5/8" nock height are common.  However, some bows will require a higher nock point.  For example, my Bob Lee Shikari requires a 7/8" nock point.  I asked JJ about it, and he said that wasn't unusual for that bow. 

Two nock points for me as well. Nock height varies from 5/8 to just s smidge over 3/4 -- each bow has its own sweet spot for nock height.

Have mostly utilized two nock sets since 2007. I apparently do not shoot well enough to actually notice a difference yet, I still tie on a 2nd. I use a single nock set when hunting as I have difficulty quickly nocking an arrow in a dark blind when required. Note: A buddy of mine has a 3rd, two 2nd's and a 1st at the IBO Worlds. He shoots a single nock set.

5/8th and two tie on nocking points.

Always two nock points.
I run bottom of top nock point at 3/4" above square.  I have a horrible release due to a dragging ring finger.
Nock point depends on the arrow.  Stiffer shafts and heavier points tend to cause more low tail.

5/8" and two nock points.
