Agree your comments about the GR3 except perhaps the roundabout bit. This was the crux of the whole thing. If you kept 250 kts with full flap and gear down it was quite steep on finals. The trick was to aim this ugly dart at the beginning of the lead-in lights. This was easy to do because control at that speed was precise, wind did not come into it so there was none of the usual need for force lob finals judgement. You then used normal low flying skills to start the dive recovery (hardly a flare!) as late as common sense dictated aiming to low fly down the last bit of the lights as low as you dare. This ensured that when you passed the threshold you were as low as possible and you then needed to put it on gently before the speed got below 160kts after which it would likely fall out of your hands.
The big wing on the B (and later GR 5/7) was much more relaxing as it could be kept in the air at the end of the roundabout down to 135 kts thanks to extra area and better flaps. Did them to a touchdown with the B on the lake bed at Edwards during 1982 when I was privileged to log over two hours gliding that year in some 40 odd episodes. Not hairy though because of the space. The experience would have been quite different in the UK.
