That's pretty wild looking.
I'd try to go #3. It won't try to torque it funny like #1, or trying to balance servos or program digital ones like #2. If you want to have blade roll as a feature, then option 2 on seperate channel with mix options.
Many radios have servo slowing as a built in feature, but it's often hidden deep in the menus as a gear or flap thing.
