Good god, I hope those are next. You'd certainly think if they went through the trouble to remaster that air bag, they'd go back and do the other models as well.
Just thinking about this... I thought I remembered the Avia Cantilever patent being dead, but is it possible that Nike had to make a couple of tiny adjustments to the 180 bag to CYA on that? That lawsuit was the entire reason the 180 was a 1-season model.
