Ok, I'm a little confused now. So the below release is a "true BT" release and it has a thumb post. Thumb trigger releases also exist but they are not considered "true BT", correct? Then a rotary type release is made as well according to this site
http://www.koniaris.com/archery/mrd/ which is not considered BT. The black release below is a thumb trigger release that a friend let me borrow. I tried it for the first time today.[:-] The bowstring only releases once the thumb trigger is pressed and then let up until a click is heard. Man, I anticipated the shot badly. As soon as I pushed the trigger I was ready to let my bow down. I knew how the release operated but its just a bad habit I have. I really need to get these issues solved.

Thumb trigger release
That is a cascade release and apparently you had it det to fire when you relax the trigger,I don't think that will help you.
That web site is technically right but they are still wrong.
Yes,A pure bt does rotate to fire and that is why I suggest a 3 finger over the 4 finger as I stated earlier,you can cheat with the fingers.BUT,you still use your back muscles to fire it when done properly.
There are some tension releases that imo,are superior to a rotary style but they are expensive and require alot of discipline in the whole shot process.
