No doubt ones perfect is not the others.
However, for FWIW I carried a standard Mod 70 for more than a few years, then switched to a FWT. Carried a standard in fact on a Mountain Goat hunt. Then thru the fire I came across Nula and Kimber rifles and said let us see what all the fuss is about. The lights came on. Carried one of them also on another Mountain Goat hunt-at 65-and the light shined brighter still.
The best weight in my opinion for all-round use would be around 7 or a little more, but definitely not 8-12.
Does a little heavier hold steadier freehand? Can't argue with that, but for some reason as the day wears on even those light rifles steady up a little after you have had them in your hands all day.
Just finished loading the truck for a few days in the "flatlands"
of West Virginia and one of the Nula's is making the trip for a good reason.
Of course I'm just a little squirt compared to some of those big rugged mountain boys out west and need all the help I can get.
Take care and enjoy your Winchesters.
