I have no complaints about my CX300's and yes I have stuck them into more than just foam!

My practice arrows are well over a year old and shoot the same as the arrows I load in my quiver come fall.
My hunting partner swears on beamans, so I think it is a matter of finding the right mix for you. Then again it might be a poor example, he also likes Mathews too, so I'm not to sure their is any reasoning in the mans head
