Metro tinkered with their lineup and game plan against Marist, so Old Boys represent the last chance to perfect those, as the Manawatū Rugby Union has stuck to the one-round format.
"Our aim is to be strong for the semifinals and final, so we've got a few weapons to sort out."
Against Marist, second-five Jack O'Leary scored two tries and kicked four conversions as part of a strong midfield partnership with fellow tryscorer Hayden Towers.
"Even the ref said 'I don't know who you give the man of the match to out of your second-five or centre'."
Tipene Reweti, a star on the league and touch fields, scored a double while, after missing out last week, Francisco Field dotted down again to keep pace with O'Leary with five tries for the season.
The St Johns Wanganui Women will conclude their inaugural campaign with their toughest match against unbeaten Feilding Old Boys-Oroua, following their 91-0 loss to Kia Toa at Bill Brown Park.
As a side full of Manawatū Cyclones veterans, Kia Toa made sure to give the Metro girls plenty of encouragement in the post-game circle, as the primary focus remains ensuring the team's existence for 2021.
"We got a hiding, but they were still pretty upbeat," coach Tama Te Patu said.
"We'd take the ball up and lose it in the rucks and mauls, someone would kick it, and they'd score down the other end.
"We need more games, more games. Maybe not at that level – just time on the field."
A number of Metro's key backs have weekday work commitments which make training problematic.
Te Patu is looking to confirm an August 8 match against the team likely to finish fifth in their grade, while the fixture against Taranaki's Southern RFC is confirmed for August 15.
Both Metro games this Saturday are at Cooks Gardens. The Women's match kicks off at 1pm and the Colts at 2.30pm.
