I have used both and the aluminum drums don't hold up especially in higher rpm applications. On the other hand the lightweight steel drum from Coan worked great...the problem is they no longer make it. I called 2 weeks ago because I couldn't find it on their website anymore and was told they couldn't get enough steel drums to make them but if you have 10 drums you could send them in and they might would machine them. So there is an option to get them made.
