Seem great but durability is a concern
"My dozen was within 1 grain of each other and they look fantastic. However I'm really nervous about their durability. I've shot 2 of the arrows about 25 times but i pulled out a third arrow and on the 5th shot it broke about 6 inches up the shaft. I paid the extra money to get these because i heard they were very durable. Hopefully it was a fluke that i broke one so quickly."
