Bent,
I shoot the G5 Montec and it is a really solid BH. I like the one piece idea and they are easy to sharpen. I shot a bull elk this year with it and it went through both shoulders, the heart and came out the other side before the elk broke the arrow in two. I recovered both halves and can use the BH again without a problem. I also like the practice heads you can get as well, great for tuning you bow to shoot BH's.
Good luck with you choice but one thing for sure,,,, no matter what BH you shoot make sure your bow is properly tuned and shooting target points and BH's in the same place.
