Sounds like a great idea, but has anyone tested to see if the length of the rod effects the spine of the arrow ?, and also, though the rod does not make any noise, what about the flexing of the arrow, I would think the rod is going to start wearing out the inside of the carbon arrow from possible friction ?

Just some thoughts on this.

Great tutorial. My alum inserts are like this and need to be tapped but the CX inserts are open and fully threaded already

I just got new ICS shafts and the inserts are plenty long and have hole all the way through. I just had to run a tap through as the threads didn't go all the way through.

Notice how this thread keeps getting dragged back to the top?

Great tutorial and ought to be a permanent "How to".
