Most IMC let downs are conducted with the Co pilot PF. The captain PNF usually provides the guidance aiming to take over the last minute visual stage with the winching area his side. That said both pilots practise the skill on a regular basis and as such are more than capable. Not many R22 drivers have walked in off the street, a few ex RAF though. They have managed it and any civvie North Sea driver would tell you it is quite a normally thing not a black art.
