I love to stump shoot with friends and thoroughly enjoy taking risky shots that will eat arrows if one is off target a bit too much.
When I shot 55# +/- I made-up a bunch of nutters and had a ball. When I stepped-up in poundage, I was busting arrows right and left and couldn't make enough to keep me shooting at suspect targets, so decided to give carbon a try.
Well, let me tell you, it hurt to bust those babies! Then someone on here suggested footing the carbons with pieces of aluminum arrows. There was a great thread with a video,
http://tradgang.com/noncgi/ultimatebb.php?ubb=get_topic;f=2;t=000112 in the How To section, but it appears the vid is no longer accessible. I'm sure if you searched the site some you could find pics and other threads that show how it is done. Maybe PM the original poster and he may have the video saved somewhere else.
Bottom-line is that I started footing my carbons on both ends and don't break arrows very often any longer. My bow is 71# at my draw and I can confidently be stupid with my target choices. I still break a few, but total cost of arrow ownership has dropped significantly since footing both ends. I usually carry a few extra nocks with me as they will occasionally pop out from the force.
So, it isn't exactly a "cheap" option when starting, but over time it has been the least expensive way for me to launch arrows at hard things or into suspect areas.
