I think you´re right, the more common ones for LSI are E1 and E6, but they can be almost any type, even E7 perhaps, but hardly E9 or E2 or E4. I know one E5 LSI personally.
Who else is a LSI E-6 here, Fwiw I don't think DJ Joe is a LSI.

A girl who I want to date, asks me: well first tell me how tall you are?
My reply: well I will answer that, if you first tell me how much you weigh!

A girl I was dating said she was oh so great at sex etc, but she didn't do blowjobs.
My reply: Oh I'm really romantic etc, I just will never take you out to dinner.
I disagree that the subtype is more common among E6s , the subtype is too. And I dont think that the subtype is more common among northerners, while the :Se! among latins, thats just ludicrous.
But all in all I mostly agree with these descriptions.
