Quartet aiming to join elite north-south club
Kafer was first to do the club rugby double, the Wallaby centre winning the then Super 12 title with the ACT Brumbies in 2001 and adding the Heineken Cup winners medal to his collection with Leicester Tigers in 2002.
Howlett doubled the club membership in 2008 when the All Blacks wing helped Munster to their second Heineken Cup title. Howlett was already a Super 14 winner with Auckland Blues in 2003.
