To me Elongated Man and Red Tornado are part of the classic JLA (starting with the group in Brave and the Bold and up to and including Firestorm). I don't have a problem with them being the 2nd stringers of the JLA. They're much better than many of the other characters DC has tried to shoehorn in over the years. For instance, in Brad Meltzer's current incarnation he has Vixen, Black Lightning, Red Arrow (formerly Speedy) and is hinting at Geo-Force being the latest member.
Brian, your son's allright by me!
