I guess I am a little opposite. I really don't like the weight of the added magnifier and wouldn't run one mounted full time anyway. I do have an EoTech flip to the side and an XPS but it isn't my working rifle nor would I want that set up on my working weapon. I would think that if I ran a magnifier set up I would keep it detached from the rifle and only mount it if needed. I cannot see needing that quick of a flip access for my uses. Man sized hits with the EoTech is doable enough out to 500+, but realistically I would never fall into that category. If I needed magnification for more precision or perhaps observation, I am quite sure I would have the time to mount it or just use it like a monocular.
Again, I am not a fan of a magnifier on my battle type carbine anyway, but that is just my own preferences that suits my particular uses. I will also say that I like the glass better on the Aimpoint magnifier than on my latest gen EoTech.
