A999/A500 Aluminum or Steel planetaries?

We replace all the aluminum planets in the Torqueflite transmissions we build with the steel ones. Got piles of um to go in the scrap run. At the risk of another infraction, that's my thoughts.

Well, Rodney races Mopars and owns the transmission shop here where I run the office. He doesn't use the aluminum pieces in anything. Not even stock replacements.

Alright, I figured steel would be the smarter choice, especially on the street, always hear that in every other situation(conn rods, etc.). One more question, only the 5 clutch direct drums used the wider 1.610 bands right? So even a modified 4 clutch drum couldn't use the wider band? Or would it be more preferable to have 6 clutches in a modified 4 clutch drum with a 1.375" kickdown band? Hopefully I'm not making a fool of myself asking these questions, never built a transmission before.

Thanks again for all the help.
