I prefer nocks that do not rely on deep grooves in the sides of the bow. I have mostly used simple overlays on the back of bow with minimal grooving on the sides. I also make my string loops small enough so that it constricts around the nock and helps keep it together. I avoid large loops that hang open on the belly side of the braced bow, because this does the opposite and tends to split the bow nock apart.
I find nock weight is always important, but it isn’t always as simple as lighter is better. It depends on the bow design and distribution of stiffness in the limb. A lighter tip may do more harm than good if it sacrifices stiffness of the limb toward the tips.
