James, Welcome to archery! I started with a PSE bow at 8 years old, 42 years ago. It wasn't until the last 15 years that I have really grown in my knowledge thru personal testing & help from what I would call experts. A couple of bad experiences with elk at close range (<25 yards) caused me to totally rethink everything regarding killing big game with stick & string. I don't have time to fully explain what I learned here & now, but in a nutshell I did a ton of testing & slow mo video and found that for me & my Hoyt Redworx, the stiffest and smallest diameter arrow produced the most penetration out of over $500 worth of test arrows. I will never use a G5 Montec again. In my opinion fixed, replaceable blades are best for hunting such as Slick Trick or Muzzy type, neither of these two broadheads have ever failed. I can't say the same for the Montec's. Also, I'll never use a whisker biscuit again either and don't recommend them unless your shooting a compound with fingers instead of a release aid.
Heavy, stiff, small diameter arrows will penetrate better and provide much better chance for full penetration than lighter/faster/fatter arrows.
I ask you to learn who Fred Bear is.
