I was instrumental in getting the original 2-meter rule changed to having it be optional so it's only used when it makes sense from a design standpoint. So I'm no supporter of blanket uses of the rule. Two places where it can make sense are when trees like cedars have a high probability of snagging 90% of discs going into them AND they are not in the main fairway but bordering it where a shot there is already bad. And the other is when the pin is right under trees that allow power players to go over the top without much risk.
