Well found.
However the HP115 picture at your link has a rubbish caption. The pic shows the position of the LE smoke canister and the visualisation of the centre of the vortex quite well but as to where the vortex bursts it’s rubbish. Alpha in this pic looks 15 – 20 tops, and the burst point is some way behind the aircraft and well out of shot.
WOK
The handing of the 115 during landing was an absolute doddle. The usual comment when somebody came back from their first trip was "why don't they make them all like that?"
The reason so many different types of pilots thought it lovely was undoubtably in part due to the fact that it had to be landed so fast (90 kts) to give any sort of go around capability because the drag was starting to build and the poor little Viper could not cope. Since that speed was over twice as fast as it could be flown (lift wise) the response to a little back stick was an immediate flare with none of the "I'm driving the back end down, and actually thumping the gear on harder" effect.
If you landed with six deg of drift in a cross wind it just smoothly puled the nose round of its own accord. With higher drift angles some attempt at easing off or even kicking off was easy to do.
During the landing run in strong cross winds it could develop a negative weathercock. This was put down to the high rolling moment due to yaw pressing the downwind gear onto the ground harder than the other one so dragging the nose out of wind. The 115 was not alone with this, several other high rolling moment due to sideslip aeroplanes that were in the same hangar would do ditto, the H126 and the FD2 being a couple. But I emphasise this was in no way an issue - just the only thing to talk about so far as landing the 115 was concerned.
