Even the most respected contributors here have different philosophies when it comes to pruning pears on standard rootstock.
For instance, in this thread, @clarkinks advocates for a strategy of mostly leaving the trees alone as being the swiftest path to heavy production. And in this thread, @alan outlines his more interventionist, systematic methodology to both induce swift bearing and end up with a highly productive, efficient structure.
Basically all of the experts, including @alan and @clarkinks, recommend branch bending laterals when young, both to speed up bearing and for developing better structural integrity.
