Looking to buy a Large Zephyr, which firmness should i get?

Have been looking into buying my very first bad dragon. The Zephyr immediately cought my eye and the size looks great.

I'm quite experienced in anal and I'm looking for something with a nice knot and some depth. I've heard lots of good things about the Zephyr and how it's good for depth training, but im kinda scared that the soft firmness might be to floppy. I don't like hard toys but I don't want them to be so floppy that it doesn't naturally find it's way deeper.

Any help would be greatly appreciated
