Where do you see the swing back to the blower combo- probably maybe 3-4 best-A fuel out number blown6-7 to oneAnd to your point over the past several years we've seen a few A/F combos grow to a handful, then half or more of the field was A/Fuelers as they bested the blower cars. Now we're seeing a swing back towards more blower cars (at least earlier this year) as that combo is working well. It will be interesting to see when, or even if, this class coalesces into a uniform combo.
