Myself personally, I don't really like the forehead-ridged, honor-obsessed Klingons of the TNG and movies era. So the time travelling mission where I got to fight TOS era Klingons was a huge surprise and pleasure for me.
But given that such extreme liberties are taken with character creation (such as the large amount of uniform customizations and great amount of Liberated Borgs), I think there should be TOS-type Klingons available for use, both male and female, WITHOUT the forehead ridges, and with the normal hairstyle selections.
Just use the alien template. I did and i love it and since the off duty uniform option gives you everything i did a TOS, TMP, and TNG version of the same character aging him as I went. FYI the TMP version is kind of a transitional look with long straight hair and subdued ridges. also they now have TOS rank sashes so the TOS version looks AWSOME. Can't wait till I can get my D7!
