Manager and former coach Johnathon Kaa said they currently had 40 players, only four of whom were in the 2019 squad.
"We've got a lot of youth in the engine room, not so much experience where we can drive how we used to do it, but I think it's a good [forwards and backs] balance, actually."
Helping that balance is the return home of two prodigal sons in former Steelform Wanganui players Kane Tamou and Cody Hemi – Tamou part of the 2015-16 Meads Cup-winning squads, while Hemi played an important role in the 2017 Meads Cup-winning campaign while still at Whanganui Collegiate.
As Rātana got permission from the WRFU for the club to have Heartland-calibre players in the Senior competition, the two young men were only too happy to return to their whānau.
"There was no Heartland team, so they thought 'we'll just come home and play'," Kaa said.
So far, the Rangitīkei derby with Speirs Food Marton was won 20-7, and then the Challenge Shield was lifted off another one-team club in Utiku Old Boys, 48-17.
Last weekend, Rātana defeated 2019 Senior champions Bennett's Taihape 39-15 in a match for both the Challenge Shield and the prestigious inter-club Whenuaroa Shield, introduced in 2018.
"We thought it was just for Premier, but they said it was up to whoever holds it," Kaa said.
"Going back to Senior was an eye-opener for us, just the boys back on a winning edge.
"Ultimately, we'd like to get back into Premier."
That process will depend on how the club is positioned after this Covid-affected season, and Kaa feels it might be a year or two before their roster is solidified.
They have another tough test this Saturday in an away match with 2019 Division 3 champions Kelso Hunterville.
