"Top of the chin bubble" is really steep, yes. That's, like, Utility world steep. Or you're going into some really tiny LZ's. Good news is you'll have to be very slow (like, below ETL slow) with an approach that steep. Which is fine. Get it set up, get is slow, get the power in, fly up to your angle, and then use the collective to get down into it. Easy-peasy, especially if you're into the wind. And you better be into the wind.
The trick is to keep it moving forward. The 206 has a strong pitch-attitude coupling with power. If you add collective the nose comes up, and sometimes pilots are so focused on their LZ that they don't realize or compensate for this. And when you're really, really slow, even a tiny bit up nose-up attitude can cause the forward motion to stop, or even reverse! Really steep takes practice. There are a LOT of things to keep track of. That said, I prefer steep to shallow. In helicopters at least. In friends, I prefer shallow.
