A few thoughts on the equipment rules.
For Factory rifle optics, just 1x would be good if matches were set up so target size and visibility supported it. The option of a single fixed power would be good for people like me who have an old 3.5x TA11 on one of their guns. The 3x option would be my last pick due to having to buy a new optic to best fit the rules.
The 1"x3" rule for breaks has a long history at this point. I agree that it is best to continue its use for factory division.
For limited optics, I like the choice of limited or CO guns.
