My dads old car, the po used rubber hoses for tranny lines & they got cut or burnt & they puked fluid. I think braided would be just fine if routed correctly but I also think that steel allows the fluid to cool a bit on its trip to the rad. As for the best cooler lines - I'm with Longhorn Man. On my car I put unions a foot from the tranny & it makes life wayyyyy easier when dropping the tranny. Get the prebent ones cause the home ones look terrible. I've good stuff about in-line tube.
