From my understanding this rule change came about becuase a bunch of P class racers in Sarasota want to race with SBI and asked that these rules be adopted.
I see this as the sanctioning body listening to what the racers wanted and if it makes sense, giving it to them.
I think we will see more rule changes to the SBI book in order to accomidate racers coming over from other sanctioning bodies. And like Puder said (I can't believe I am about to agree with Puder) wouldn't it be great if the rule books were more closely aligned so that teams could go back and forth between groups.
The pond is frozen, let's skate.
