There's lots of fun broadheads to use.
The only disadvantage with using the Gobbler Guillotine is it has to be used in combination with the Arrow Dynamic shaft and it's pretty much just for 'head & neck shots'.
The same guys who designed the Gobbler Guillotine has come up with another head called the ATOM--don't know if it's on the market as yet--but saw it at the ATA show.
For me, I found the 'Grim Reaper' heads do quite a respectable job--can't go wrong with the Reaper for the turkeys.
