and take you down the deepest? I mean closest to nearly falling into a bottomless pit?

many people recommend lutz's bubble induction for that, but i think its very much a your millage may vary thing. if you get down that deep you run the risk of falling asleep.

So,that takes you down the deepest?

It's always going to depend on the subject. Blank and Bubble both work well for a lot of people, but it's always going to vary. My personal favorite is "Fluffy White Cloud" which gets me so hypnotised that I black out most every time.
