I feel a great kinship with you Stillin, as I have written on other threads, when I started giving PT's as a M.S in the early seventies, I used to do my own outline/talk. This was allowed to continue for some time until stamped on by a firm letter from HQ.
I still gave PT's but prepared them as you describe, always bringing something fresh to the table,even a talk I had given before would be refreshed.
I used Bible Commentaries to get a good understanding of the scriptures I used and their context, often giving good background info. before reading the verses, a contrast to most robot Dub speakers who just read a verse with no knowledge of its context, and no explanation of its import, because they don't understand what that is, how can they teach anything ????
I felt my job was to convey God's word to people, not the Watchtower's word. Many times Elders told me they did not recognize the talk I gave, they had given one from the same outline, but it was very different to mine. I never gave out anything but upbuilding stuff, no cajoling, or mind control stuff at all.
In the end I refused to give any more PT's , mainly because the outlines contained no spiritually upbuilding content at all, even though (blowing my horn) surrounding Congos sent requests for me to visit again.
WT/JW land is spiritually a lifeless desert.
I am glad I left, my life is better spent elsewhere.
