After doing some "hers"-story [Bad pun ... I know ... but I remember this "term" from "Barb's site" (it was a Really Good site a while ago) ... If you want the 8-1-1 on it, go to the bottom half of this page and read the categories composed by Barbara (The Doctor) ... click here] ... again, apparently this enterprise was among the first companies to really produce Good fem-vs-fem products over here in 'Murkinland some time back in the early to mid-1980s.
DTL came in the late 80s you can find one of the pro clips featuring Bambi and others on youtube. DTL had a bit of an issue with conservatism that you're noting with prude tube regarding intensive microscopic scrutiny leading to its dismissal. DTL turned into other names some of which you mentioned above. Your board FCF link mentioned of a cute blonde and her participation during the Inland Empire days. Dee was always a hothead though seemed most of the time her competitors fixed that with a few armbars or long frustrating scissors / embarrassing rolled up cradle pins to get her angry. I would put the DTL in category of other clubs that knew how to use actual transitions / holds.
