I have VA, I have had it for years, but only use it for a couple of things in ED, managing the power distributer and switching to the next pre-set navigation point, which is a grand total of 7 things.
my setup is HOMAS (Hands On Mouse And Stick), VA as per just the above and a keyboard secondary actions.
the mouse is for looking around and is on the left, the LMB1 and RMB2 are throttle up/down covering forwards and reverse, the MMW scrolls back and forth through all targets, and the MB4 (thumb button) dose context sensitive FSD, the MMB toggles through hostile targets, and MB5 (thumb) is my universal push to talk for MP gaming in all games and 3rd party apps like discord or TS.
my joystick is a 17 year old MS FFB2, the 3 axis (pitch, roll and yaw) do as you would expect, on the stick part the POV-hat is left/right/up/down thrust, buttons 1 (trigger) and 2 are the fire groups, button 3 locks the target in the centre of my view wherever I am looking with the mouse, button 4 is boost, on the base there are 4 buttons (5, 6, 7 & 8), button 5 is to toggle the hard-points, and 6 toggles the landing gear, buttons 7 and 8 are not mapped, there is also a throttle axis, which is bound to the throttle (forwards only), but it is seldom used.
with the above I can fly, look around and select targets by a number of methods, while changing the throttle settings, change the power distributer setting (VA) and engage/disengage the FSD while just keeping one hand on the mouse and the other on the stick, which may seam like a poor-mans HOTAS, but the ability to look around with a mouse far exceeds the ability to do the same with a HOTAS regardless of the type of hat-switch on it, or that of Track IR (and I have Track IR to know that).
