Reservations on XR line and dot thickness for hunting.
The Gen2 as piccied on full mag is too thick, when on lowest mag it is about right, it is also less cluttered than XR. Xr look too fine for hunting applications at respectable ranges, add to this counting and concentrating which line to use- maybe a case of less is more.
Not sure if these 1st focal plane mods degrade the optical quality, my VX3 is a little grainy and lacks definition above 38magish, something the genuine fixed mag Mark 4 are renowned for.
If you can live with the TMR as is, go for that, if not it will only be the GEN2 or XR.
