I would have to go with- just like to try something new-.
I have a bad habbit of buying new heads just to have them.
There are so many good choices out there now I have a hard time picking just one.
To date, I have only killed deer with muzzy 3 blade 100 grainers, sattelite Titans and rocket sidewinders.
I liked the way the doe I shot with the sidewinder went down quick. With my new bow providing more KE, I' m wanting to try a 1.75" or better cut b/h for even quicker kills.
