So, domane, emonda aluminum or sl series...

I have an aluminum specialized but am looking to potentially upgrade to a new roadie. Current bike is 10 years old.

I don't know the difference between the doMane or emonda series. Plus, is the aluminum version inferior to the carbon, or are they pretty close? I have a trek speed concept, but not sure I want to stay in tri. Too much to balance with family, work, being good at 3 sports and trying to enjoy other hobbies...golf etc.

Thanks for your input and or experience with said bikes. I do want to ride them, but shop currently does not have what I am looking for in stock right now.
