Preferred method of induction? I.e. pocket watch, pendant, crystal, spiral, fixation, etc.
Yes, all of them mentioned above, and more. I have a passion for stereotypical inductions of all kinds, the more stereotypical, the better.
But my most favorite must be the classic “look into my eyes” fixation induction, especially when looking into the eyes of a lovely female hypnotist. 
And who better to epitomize that than the “Hyp Hypnotist” herself, Pat Collins.
