I have to admit, I didn't have any trouble killing deer with the Rages. I even had several fall within sight. But my experience on hits was very similar to those seen in the video, even without hitting any serious bone I only achieved about half arrow penetration the vast majority of the time. As I said, I don't have any evidence yet that my new setup is going to be better (I didn't kill a deer with the bow last year) but I don't think it will be any worse. If nothing else the COC should help with initial penetration and my bow has to be better tuned to shoot the fixed blades on target.
I don't know what you are getting for speed but it sounds like your setup is close to the numbers I'm liking.
I may be babystepping this a bit, but seeing as I haven't had penetration issues it's a bit of a leap to go full Ashby. I don't want to make a change that maybe takes away from an element that has been important in my successes.
My brothers switched to VPA long ago and the mental gymnastics of going COC aren't too hard for me. With an equal tune, the single bevel Alien V2 broadheads I've got have the same cutting diameter (1.5") and number of blades (2) as the Rage's I was last using. But the V2s are an improvement in durability, sharpness, and cut shape. As well they may wedge through bone better, being single bevel. I don't know what I'd be giving up. They are a non-vented, so shouldn't be too loud, but possibly noisier? And I'm not sure how they will compare on deflection.
If I can increase foc and overall arrow mass and not loose speed over my current setup, with a more efficient bow, that's an easy win. (So long as the bow is as forgiving and I can shoot it as well as my current rig).
Ultimately, I don't want to ruin a good thing, but think there's room for improvement in my setup with only small performance costs.
I definitely don't want to end up worse.
Here a rage exited through the offside shoulder. Deer was quartering away, arrow entered near the last rib.
