Is this a Florida Giant Mulberry?

I found this single trunk large leaf tree (about 10 ft tall) sticking out from a briar patch (poison ivy too) that I am about to take out.  
Is this a Florida Giant Mulberry growing in North Alabama?  Is this worth trying to take cuttings and see if they root?

Look at pics of paper mulberry as well. Leaf angle in pic makes it hard to say.

Went to growingmulberry.org and looked at the description for paper mulberry. I also went to the Purdue extension paper on Mulberry.  
No red hairs on petioles or the small branches.  The leaf is dull dark green, rough on top and the hairs are not visible so I am thinking this is a Morus Rubra. Morus rubra has leaves as large as 10 inches
But The first website indicates that Florida Giant is a Morus Alba.
So this may just be a standard Red Mulberry.  I can always graft other varieties if these turn out to be not flavorful.
I may have also found a very large version of this tree around 50 foot tall.  May look at pollarding this one in the fall.
