i shoot with rocket ultimate. they are small fixed blades. however im very happy with it. replacement blades are easily found and quite cheap. however its major problem is that if you have shot an animal that goes in the bush after the shot, it is very hard to follow the blood trails as there is not many blood dropping cause the cut closes imadiatly after the broad head passes the skin.
i used to have a broadhead that i bought on ebay 3 years ago. i cant remember its model but it was a carbon express or element i think and that was my best broadhead unfortunately i cant find them anymore.
