Cornfed.............you gotta be on the Rocket pro-staff or something !!
They are better for low KE set ups "no doubt"..........beyond that :
If you call barely sharp ,easily bent/broken blades, hardly any threads to screw in your insert, noisy, o-ring equipped little broadhead .............superior....... to an extremely well made , super sharp , dependable, top of the line broadhead.......well so be it (I've tried several Rocket's....including Steelheads.....you can have them).
They kill things........I admit it !
Won't ever be in my quiver again !!
