I'm with ya 100% on this one BigBulls. You did leave out Rocket Aeroheads Ulitmate Steelhead though! I shot a number of mechanicals over the past 6-8 years. I tried a pile of them and on whitetails haven't had any real major problems. But in 2000 I decided to try the Wasp Jackhammers on Co Elk. BIG mistake. I shot at one bull at 45 yards and a small twig the size of regular pencil lead pulled my arrow off course just enough to hit dead in the shoulder bone. The arrow stopped dead and bounced out. Total pentration? 1.5". Second Bull took a nice 25 yard shot to the onside lung and likely back through the liver. Never recovered that animal, but other hunters on the other side of the mountain did several days later once the meat had spoiled and been mostly eaen by the local wildlife. The arrow never left the animal. I have never felt so sick in my life. The bull was jumped up by other hunters so many times he headed all the way around the other side of the mountain. I was hunting San Juan Natl forest and it happened to be the opening day of muzzleloading, so there were hords of hunters coming up the mountianside. I had gotten up extra early and hiked in the dark to the upper meadows and was able to get close to this nice 4x5. It made me sick as I tracked him. I would go down the mountian several hundred yards and run into another group of hunters. They each told me that they had seen a 4x5, but it was moving on so quick they did not have a chance to get a shot. I realized then I might not get this one back at the rate he was moving around the mountain. So since then my quest has been for extremely accurate fixed blade heads, and plenty of arrow weigh along with practice at 70+ pounds of draw weight to ensure plenty of energy is transferred THROUGH the animal. I don't want to waste any ON the animal. Of the two deer I shot last year with the Rockets, I can say that they will do the job with absolutely no problem. I am also shooting a 10.6 grain per inch hunting arrow, so I got plenty of energy stored in my arrow. I called American Broadhead company last year and got them to send me a 100 grain Sonic head to test last year. I shot it through a ton of things, and so far the blades are still intact and amazing sharp for all the wear they have received. I bought 4 packs of them for Co since my tests and others have shown them to be awesome heads. They do fly great out of a well tuned bow, and don't fly too bad out of a not so tuned bow. But you hit the nail on the head with this post!
