I used to use the epoxy, but I switched to superglue. I read in the Easton tuning guide where superglue actually bonds/becomes part of the carbon, so I tried it. Matter of fact I didnt get one seated all the way quick enough, and that dude aint ever coming back out. I just lightly score the inside of the shaft with sandpaper, lightly score the insert, wipe it off on my jeans, and glue it in. So far it has worked perfectly, and it only takes a minute. So I'll keep doing that.
I use the 100 grain brass inserts.
