Often times what I’m used to make the balls hard to rack wasn’t the rack.
Template racks are useless with old wore out balls. Nobody ever mentions that.
Balls first, rack second makes a perfect rack all frozen. (If that’s what your looking for)
The balls were worse down-the 1 ball is usually smaller as it’s always the head ball and gets hammered. Back when pool rooms were busy the balls were mix & match and wore down. So a freezing all the balls was impossible. Slug racks were easy.
I’ve put old sets of wore out balls on a template rack and it’s a mess.
Now that we get new colors

and new balls every year it seems. There aren’t old wore out balls around as many places.
