This discussion is like trying to determine what bullet is the best...Everyone will have an opinion and there are many examples out there of PG and DG being taken with both 2 blade and 3 blades broadheads. So let me throw mine in, I prefer fixed 3-blade broadheads. I currently use a Muzzy 3 blade with chisel tip and have not been disappointed. I am experimenting with Rage mechanicals, but have not been convinced that they are far superior to the fixed blade. You do have to spend some time on the range to make sure your bow is tuned properly the broadhead you are using (2 or 3 blade, mechanicals or fixed), but we can all use some extra time on the range. Additionally, you must ensure you are using QUALITY broadheads and arrows. Finally, it is all about shot placement! You can spends thousands on equipment, but if you can't place the arrow where you need to, it is all wasted! So bottom line, choose quality equipment, gets lots of practice (more than you think you need) and put the arrow in the correct spot and you should not be disappointed.
