I choose to spend varying amounts of $$$$$ on each of my hunting-working rifles because I can have them made more efficient for my uses here in western-northern Canada.
I happen to have become most familiar with the Mod. 70 safety and find it easier to just have all my rifles so equipped as *muscle memory* is effective in sudden encounters with Grizzlies, especially when alone far from any assistance in remote areas of my country.
With 50+ years and about 150 rifles under my belt, this is what works for me and I consider the expense well worth spending, others in other situations may not.
I also have Mausers with both C and H rings and prefer the original design, but, will not make a big deal about it.
Lot to say for muscle memory and having them all set up the same.
