Don't mean to offend any of you guys about the use of Revo mixing but I disagree with part of what you are saying. Revo mixing works very well with rate gyros as I have used the Revo extensively with my own rate gyro and DX6i. Revo mixing works quite well helping hold the tail on hard acceleration and deceleration when using a rate gyro.

However, Revo mixing and some other forms of channel mixing must be disabled or turned to 0% when using an HH gyro. All this is stated in the literature of most gyros, or TX manuals.
