I have my IMU and I can get
attitude (pitch, roll, yaw) as well as
gyro (x, y, z)
As far as I can tell,
attitude is all I need to stabilize my drone.
Is there any reason to implement
gyro or will
-- EDIT --
It seems the benefit of
gyro is an immediate response to an outside factor effecting drone stability.
A gust of wind hits your
attitude will not be quick enough combat the effects of wind. As far as I can tell, the gyro will be the best way to combat extreme wobble and outside influences such as wind / tether (leash).

It's been a while since I posted this but I should add in that I ended up leveraging the infamous PID algo for my arduino.
