I think what people aren't understanding is the whole spec tires deal is easier for the host club and racers, period. So far, we have far more people liking the idea of spec tires than those who complains about it.
And keep in mind, we sold CS-27 set for $25 each at Nats. You are given 1 set with your entry, can buy 2 sets for heats, then another set if you qualify for A-main. So 4 sets total.... $75 worth of additional tires. You get 4 sets of tires for whole lot cheaper than if you would clue tires yourself.
And again, if you have hosted a nationals event, you try to eliminate waiting lines and have the most efficient way to deal with things. For those having host a Nationals event, you would have no idea what's involved in it. The less trouble, the better.
