Ya'll might not remember when carbons 1st came out they were the PC kind, pultruded carbon and were very skinny. They used outserts for the points and outserts for the nocks or slip over nocks on them. They shot great and were very tough, but the biggest complaint on them were the outserts and difficulty pulling them from targets, that spelled the demise of those shafts and ushered in the wrapped carbon shafts with internal inserts, so there is you answer on outserts. Customers complained about it and manufacturers addressed it. Of course the trad market is a little different for these arrows, but they do shoot great with the brass inserts. Those PC arrows worked very well and penetrated very well, but now they are very hard to find and you cannot hardly find the adaptors for them. I still have a bunch of the 2300's, they did shoot great and just wonder how much better they would have been with heavy weighted brass outserts on them?? Mark
