I suspect that you are exactly right with the frangible bullets.
Something I just won't risk when barnes are available.
Just me of course.
And I hear you on trailing, I've said it before and got ripped for it, but I enjoy following the trail. Its just part of the hunt and the puzzle to me. Likely because I started bowhunting at an early age and you simply have not many options there... either learn to trail or loose out. You don't have the luxury of not trailing.
I have a box of 80 barnes, and one day I'll ramp them up just to see... if you have no issues with a frangible 100, an 80 mono won't... but I still expect that its all going to be shot placement. And I still suspect if I wanted to go backwards to a cup and core bullet, I still would see very few DRTs due to how I choose to place the bullet.
