Salute!

Some really great stuff on the last few posts
.
I flew three birds with an AoA gauge or indexer or bracket in the HUD.

The VooDoo did not emphasize use of the AoA gauge for landing or best cruise/holding. It was mainly an indication of how close you were to the pitch-up.

The A-7D and F-16A had an AoA bracket in the HUD for approaches and it was very useful as Lom has explained. The A-7D, being a USN derivative, but with vastly more advanced avionics, retained the USN "indexer" chevrons on each side of the HUD to show best approach AoA. Because stall and best approach speed changed a lot due to external ordnance and configuration, AoA was the best indication versus rules of thumb that related all the factors to a best approach speed. So if the guess was within 5 or 10 knots when the AoA indexers showed where to fly, then it was easy to transition and fly the AoA. The A-7D and F-16 had the AoA bracket in the HUD, so pulling or pushing that thing wrt the flight path marker made approaches a piece of cake.

I adopted the USN practice of flying the A-7D down to the runway with little or no flare. The F-16 required a bit of flare if you were hot or you would bounce. And as LOM has stated, no cross control for crosswinds!! Land the thing in a skid with the aileron interconnect feature would bite you in the butt when weight on wheels happened and the feature kicked out. F-16 was really touchy about that, but gear was close together and it was no biggie right after touch when landing wings level in a crab.
