Can't say I've heard of those. Off to check thanks.Firenocks are the best, but they're very pricey.
Lumenocks are a solid choice. Nocturnals aren’t bad, I’ve used both extensively and lean towards lumenock because they hold up better if you intend to practice with them- which you definitely should. The firenocks are heavy. As with anything, test poi with your broadhead and hunting set up. Nock fit to string is very important for tuning with broadheads. Some companies tolerances do not match up to your stock nock throat- it may not necessarily alter your poi with field tips and then show itself in erratic broadhead flight.
