This is what I normally sell for your set of requirements. Cast iron Rexroth-Bosch diverters with an actual control grip that goes on the single rear remote lever.
No rocker switches to actuate, then move your control lever. Everything is done from the single control lever. You can control 4 separate functions and never take your hand from the control
lever.
The far right set is your default set, simply move the lever. The 3 sets of couplers that are on the face of the diverters are controlled with 2 button switches and a trigger switch to actuate the desired diverter and then you move the lever as you would with any other manual control.
So feathering is not an issue.
