All I know is most people told me they would just bounce off - but I shoot em with those 6.5CM doohickies, and they poke holes pretty good.
In all seriousness, I'm of little help to the technical aspects of your setup. I do sometimes we put a lot of stress (and $) into chasing specific numbers and fractional differences. Patience and good shot placement are the keys to me.
People were hating on Rages when I started bowhunting, especially with elk. But, I've seen them take down a half dozen in the years I've been hunting. I've also seen quite a few guys who are over confident in their setup, because of their numbers or equipment, and they force shots they shouldn't be taking. Same thing happens with the guys who buy a GunWerks rifle and a Nightforce scope, and think 1 trip to the range and a 1/2 box of shells to practice is sufficient. If you don't put the pointy end where the soft parts are, bad things happen.
I shot a bull once that had a fixed blade buried inside of him- aluminum shaft arrow that had broken off at the hide, broad head buried into his hip bone. Non-lethal, very very VERY terrible shot. Looked like someone took a quartering too shot, and just pulled it back on the animal. I'm sure it hurt like hell, and he may have succumbed to infection in the winter- but the sucker was still walking around and feeding a few months later for me to poke holes in him with a .300 Win Mag.
All that being said, if I was prowling for bulls in the mountains, I would be asking the same questions you are. Keep it up! I hope you can find the perfect set up to be confident in, and I know you will be putting the hours in that will really make the difference.
I will say, I was unimpressed with the Montec's when I started, but I know plenty of people up here who use them with no problems. They didn't fly well with my setup. I like the HellRazor for fixed, and shoot Hypodermic for mech's.
