Yes, they look good. Not alot of grain runout. There is some, but not of a severe nature. A little hand straightening and they should be good to go.
I cant comment on any increase of toughness, since I havent shot any of them yet. To my way of thinking, there would have to be SOME gain in toughness, but how much, I wouldnt have a clue.
I believe these shafts start out a Rose City shafts before they are compressed. Overall, I am happy with the ones I recieved.
Go to JK Chastain's website to read up on them some. Website is worldclassbows.com. I ordered my shafts from him.
