I use G5 Small Game Heads (SGH)... If you miss and they go into the grass, they leave such a large tear through it you can easily find them. However, if you hit your target, (chipmunk, squirrel, rabbit, etc) it tears them up so bad, you have to keep a paper towel handy to clean up the mess. They work well on larger animals such as woodchucks, raccoons, and porcupines; with such a large wound channel, they don't go far at all.
This past turkey season I got one with them out of my compound. I'm not sure that I'd want to try it with my widow since it's only 50# @ 27'' and doesn't have the same energy as they do coming out of my 75# Hoyt Carbon Element.
