A father of four who works as an apprentice for High Torque Builders, he has had little time for training because seven-day working weeks have been the priority recently.
"Hopefully the body can hold out until halftime," he said with a laugh.
Providing he has the necessary time to devote to his league training Tango could prove as valuable to the Unicorns in future as a bloke of similar size and with similar ticker, Bradley Higgs, was in the mid-1990s.
"I know I might have left it a bit late. But hopefully this stint might open some doors for me," Tango said.
"This weekend's team looks pretty good on paper. But we haven't had a lot of time together so we will just have to react to the challenge in front of us," he added.
Along with Karamu High School product Tango, the other "big name" in the Unicorns team is former Central Vipers hooker Colin Hokianga, who will start at scrumhalf if he fronts. Last night he was still pondering his schedule for tomorrow.
He may just focus on the Tamatea premier rugby team's eighth round Tui Maddison Trophy encounter against MAC at Flaxmere Park. Tamatea must win this match to keep their slim hopes of avoiding the promotion-relegation game alive.
"I could play the first half for the Unicorns and then go and join the Tamatea boys. I probably won't decide until the day as I've also some of my daughter's basketball games to watch too," Hokianga said.
Unicorns coach Aki Renata said his team hasn't had the best of build-ups because several players in his extended training squad still have union commitments.
"Basically the aim is to be as competitive as possible this weekend and gauge our work-ons as we prepare for Manawatu and Taranaki. By the time those matches come all of our squad will be playing in our eight-team Spring Comp and will be better prepared."
The Unicorns play Manawatu in Palmerston North on August 20 and Taranaki in Hawera on September 3.
