I shoot Maxima 350-spine. I have so far found that they are supremely durable. On my first 3-D outing, I sent one smack-dab center-mass into a tree. Shaft was recovered without damage. On my second outing, I was trying to shoot a pig target. Between me and the target was a section of rolled-up wirefence forming a big "O"-shaped tubethat one must shoot through to hit the target. I must have done something wrong, because the arrow struck the inside of the tube laterally and glanced off at a severe angle and into the target backstop. I was sure that arrow was a goner, since it hit laterally and made such a violent change of direction. But nope, it's still a good arrow.

I'm happy with the Maximas, even though they are a bit pricey.
