My GT trads are very durable. I have only wrecked two other than robbing hooding. No shaft takes that very well. One I shot in half with another arrow because it was hanging. The other was from a glancing blow and on a heavy piece of steel and then it slid into a corner where it wedged kind of and that did it in. The shaft snapped in half, but I also mushroomed the point, bent the brass insert, and split an aluminum footing full length. They can only be expected to take just so much.
I have only broken one carbon express heritage, but I have not subjected them to near as much at the GT trad. I just got some AD's, but not sure how they hold up until I hit a few harder things with them. Never shot the FMX, but hear a lot of good stuff about them.
