Sorry I haven't been able to answer your question because my internet was down for about 3 weeks.

I have had no durability issues yet but I haven't tested them.No bad shots to know for sure but you will be hard pressed to find an arrow with the consistancy of the FMJ that will align a broadhead as well as they do.

Of course,aluminum isn't as durable as carbon but spine consistancy will be better so it is a matter of which do you want,to me it is the best of both worlds.Plus,they will hold spine longer than an all carbon shaft.


For the record,I have been an ACC guy for quite a while now and still love them but they will not carry a fixed head as well as an FMJ imo.
