i couldnt help but notice theres a countless number of knock off mechanical heads on ebay and when i hung up my hunting bow a few years back lots of people were under the assumption that 2 blade broadheads were wings and they made terrible groups...
muzzy heads came with my bow when i bought it and i soon converted some muzzy original 4 blade heads into 2 blades with some old stock filler blades.
the results were astounding.
i have some pictures if anyone would like to see them, i have never seen another picture of them on the web. it kinda seems like only veteran traditional hunters use 2 blades anymore....
they blow through even the thickest hog hide... which was were my intentions were while bow hunting.
