On the website...I saw the it says that the diameter of the 100gr is 1 1/8". That would be the cutting diameter, correct? Do most believe that 1 1/8" is enough cutting diameter for a bhead?? Right now I'm using Rocket Sidewinder 3's with a 1 1/2" cutting diameter. Is that overkill in your opinion for whitetails or just maybe on the upper end of the spectrum?
