PS needs manufacturer diversity, less overhead to compete, and arguably closer relation to Stock or SS, though that isn't a deal-breaker.
Right now, seeing a bunch of the same cars, that look more like PM or FC than an actual car, loses the visual appeal. The expense loses anyone who isn't a millionaire or well-connected. I don't see the value of the EFI switch, except to the supporting vendors (follow the money?) or rules that favor one make (follow the money again?)...
I'm OK with bringing in the Mountain Motor cars, but that could be difficult to manage unless there's at least a weight/size formula.
I think NHRA needs to re-think what Stock, SS & PS cars ought to be, but that's gonna hurt a lot of guys.
Obviously, one of the key problems is the demographic NHRA is trying to reach, and whether that has more value than tradition.
