Just a quick note on the M700s you list
I tried to note the differences, they all have the new x-mark pro trigger. The xhr is the heaviest by 1/4 lb. You may want to consider that these have a 24 inch barrel. While this gets max performance out the standard cartridges it will also not be as handy in the woods as the more standard length 22 inch. Those two inches are noticeable. If they do bug you, just have a gunsmith cut off 2 inches and recrown the barrel. Whichever of the three you pick will be a nice addition.
