Throat vibrato on deep bends? and navigating between bent positions?

This week I suddenly succeeded in deep bending!

After months of struggle straining my tongue in different positions, I could only make shallow bends (and often not reaching a true half-step), and all that I was missing was actually "relaxing" my tongue. I suppose it *has* learned to keep the tip on the harmonica, and now I can trust that more.

Now, exploring this new area, I feel it's really like another "register", and I can't connect continuously for example from 3' to 3" or 2' to 2". I can reach one or the other, but not navigate between them in your Shh-Kee-Kuu manner. Even the couple of times I reached 3''', if was not from 3" but a kind of "missed" 3" going too low (and that I cannot yet reproduce at will).

Also, I noticed that 2" and 3" interfere with throat tremolo (at least as I do it). So my questions:

- Is throat tremolo still possible in those positions? Should another kind of tremolo come to the rescue? Or is it a hint that something is wrong in my new skill?

- Is it worth training now to go from ' to '' bends continuously, while bad habits are not yet enforced, or should I be confident that it can come later, and I should not worry about that now?
