Pros in the 80s were distrustful of alloy TA cages and still used the steel ones. I know from my own experience that eventually the tig weld between the cage and the base cracks and fails.
In the past I use to think that the aluminum cages that had the base crimped to the cage were a cheaper way to make them, but I now think that style of construction is probably superior.
