Norwegianwoods, I think what you are seeing on some of the hunting shows and other videos of people shooting mechancials is the fact that they cannot get their bows to shoot FP's and BH's the same, a factor of not tuning the whole set up. Mechanicals came about because the speed of the bows jumped drastically in the 90's and it became hard to get fixed blade BH's to fly right, hence mechanicals. Screw most mechanicals on an arrow and the majority of the time they will shoot with your FP's. If not you have some serious tuning issues. With an untuned bow even a mechanical is going to loose a lot more energy whit it hits an animals as opposed to one being shot out of a well tuned bow set up. I have shot a lot of different heads, fixed, replaceable blade and mechanicals and I have killed a lot of game with all 3 and unfortunatley lost some game with all 3. It boils down to proper shot placement. I agree, mechanicals can fail, but so can sights, release, compound bows and such. On plains game I do not think it is bad to use mechancials as long as your are shooting enough KE, momentum and have your bow tuned and know how to shoot it. I have used Rages on my Nyala and Kudu with great success, but that will probably be the last time I use a mechanical, especially in Africa. That is unless I find a head that will outshoot and out penetrate the Smoke Ramcats I am currently shooting.
