They are like $10 an arrow. With a 100g field point they weigh 400g. They have an aluminum nock. They are nice but I did notice today that the aluminum nock is scratching my flight track. Didn't really care for that so I decided to stop shooting them. The flight track on the Ghost 385 has a copper color to it. I started seeing a shiny scratch all the way down the middle of the track. I can only assume it is from the aluminum nocks on those arrows. I had that thing lubed too so there is no way that it was from having a dry track. Just a little warning for you. I went back to shooting my black eagles. No problems out of those yet besides robin hooding them. I had 12 now I am down to three. You think I would learn my lesson
