I agree, the only reason that some are in three packs is because folks would absolutely not buy as many six packs at 60 - 200 dollars a hit.
I think a six pack is the right number to have, but, well, I guess everything is more expensive now days. Buy up those big Z's while they are available at $24/6 or whatever it turns out to be.
Bill a modest increase will go unnoticed, but a huge jump, like I am seeing in a lot of heads, means I buy fewer, or find a new head, and there are plenty out there.
I am certain that some of the heads available are awesome, the best out there, but I don't need the best when even a moderate head is awesome on deer sized critters. I will never get to shoot an elephant or a water or cape buffalo.
