Rigpiggy, we all agree manual flying skills are being eroded by automation, and regular practice is important. However, doing a manual approach in marginal CAT1 conditions is probably not the best time to do it.
At the very least a go around costs you 15mins of fuel and time, which in a typical short haul schedule is going to compress the rest of your day and probably delay several hundred passengers.
Explaining to them that you fancied a bit of manual flying as the reason for their delay would be met with a certain amount of irritation. Our Airfrance colleague made a poor decision and showed that he had given even less thought to his go around than he had to his decision to fly a manual approach.
