I put on a dozen Omni nocks last night and bought a couple Pro Elites with them on as well. I like that the nocks come with the indexing tool that locks into the triangle and the omni depressions in the nock making installation easy. I also like the positive seat when you push the arrow into the string for shooting. If you try to put it in twisted you can feel it turn the arrow to correct. My shots were dead on before and after the nocks so I guess the good news on shooting is that it still shoots perfect. I bought these because I was never comfortable with flat nocks and have been told moon nocks do not work well in ten points. I guess to sum it up, I like them and they are inexpensive, I will get more when they come back in stock for my aluminum arrows and when they are made lighted with Tracers.
