RE: MZE, had to go.
I just reread your original post. I should have paid attention the first time. I thought it was in reference to "some Bowtechs" meaning the Guardian and Commander. It's no secret that the MZE won't work properly on those bows.
As for the 06 Allegiance I can honestly say first hand that the correct MZE next gen will work on that bow. I have one on my Allegiance and it works great.
