Well this article talks a bit about the past and that some of the wives tales may have been true back then, and some maybe not. Certainly things are different now.

Debunking Aluminum Rod Myths With GRP - Dragzine
Maybe my view in the past was rooted in a lot of half truths, at best, when it comes to aluminum rods.
In industrial experience, I have seen aluminum fail, when the wrong grade was used and the correct grade last. A half million dollar machine failed catastrophically in 6 months use. The correct grade aluminum has lasted 30 yrs now and still going strong.
That said thanks to Paul for opening my eyes on aluminum rods. I'm not sure I would ever choose them in a street engine, because I tend to be conservative. I do not like to rev past 6000 rpm and 7000 is tops for me. The lighter rotating assembly seems to me to pay off more at high rpm and that is just not me. However light rotating assembly can rev quicker, so I wouldn't totally rule them out.
