Granted this is not an actual animal I did this withbut shooting different COC heads side by side withthe short heads like the slick trick the ST style heads consistantly out penetrate COC heads by a couple of inchesin arcehry targets
This has been my eperience as well (on a Morrell block target). I have shot one other broadhead that out-penetrated the ST. It was a G5 Striker. I could never get it to fly as well as the ST though.
