Just my 2 cents on this.

I feel that topping from the bottom is more then suggestions and advice. When done with a bottom and a Top that are mearly scening it is the standard form. The bottom is the one in control and since that is only safe for a limited relationship.

I hope that you listen to your sub/slave and figure out what they need and give it to them but to let the sub/slave run things means it is just a sham.
