The main point is always shot placement BUT things can happen out of our control and the hsot may not hit where we intended. Thats is part of the game. I think if a hunter can take advantage of something that increases their chances in one of those less than idea cases they have the right to use it.

My main points are this.

If you want to use the big heads make sure you have enough KE to use them to get full penetration.

Shot placement is always a key no matter what you use

blade sharpness is a major key and is often overlooked.

always use a well tuned bow & arrow combo.

I have used broadheads that have 4 blades, 3 blades, fixed, mechanical, etc. and they all will work. I see no issue with them in general. The real issue is if the company makes claims about their products that are bogus or the hunter things a 2" hole will kill anything no matter where you hit the thing. In my opinion these people really don't care about the sport & only want to fling arrows no matter what the outcome is. It dosn't really matter what style of broadhead they use. They will still continue to do stupid things.

I generaly liek a normal fixed blade head such as the Rocky Mountain Ti-100 or Ironhead 100. They work, have 1-1/8 cutting diamters, and they penetrate like a hot knife in butter. Thats all I need but then again a lot of people want something else & if they play by the rules of the other designs I have no problem with it.
