after checking out that calculator and plugging in my personal set up, i have to say that adding mass is the way to go, for me at least. best case scenerio is to add mass without sacrificing speed. however, if you just add mass to your arrows and do not change your bow, you will lose speed, thus decreasing your potential final kinetic energy.
My point exactly. And the reason I changed my setup this year. I had a couple of guys that told me my bow wasn't fast enough to kill a deer. I killed 25 - 30 deer with that bow until I bought a new one. I used a cut on contact broadhead and never had a problem with passthrough. To each his own but I'll take a good heavy arrow anytime.
We can't continue to do the same things over and over and expect different results
