One is a son of the surf; the other a man of the land.
One stands at 194 centimetres and weighs 126 kilograms while the other is a comparatively diminutive 176cm and 89kg.
Yet Gold Coast odd couple Shannon Boyd and Mitch Rein could be key to unlocking the potential of the Titans.
After missing the first two games of the season, Rein was replaced by Anthony Don as Michael Gordon’s regular roommate and now bunks down with Boyd on away trips, the pair getting to know each other in a two-week road trip for games against the Rabbitohs and Warriors.
The inclusion of Rein due to the injury to Nathan Peats seemed to spark the former Raider to life with Boyd running for 123 metres in 34 minutes off the bench in the 28-20 loss to South Sydney.
Boyd returns to the team for Sunday’s clash with Newcastle after missing the win over the Panthers with hamstring tightness.
"We’ve been talking about what he likes to do, what kind of service he likes. I’ve really been looking forward to playing with him," Rein told NRL.com.
"Those combinations with new players at new clubs take some time but he’s a great player and really gives us that momentum.
"It’s just taken a little bit of time these first couple of weeks at a new club to figure himself out but the game against the Rabbitohs was a massive step forward.
"He gave us a lot when he came on so [I'm] looking forward to getting some combinations with him, playing off the back of him and giving him the ball how he wants it."
While Rein is ready to use a revved-up Boyd to dart out of dummy-half, the Titans prop also believes his livewire No.9 can help him to make a greater impact.
With Jarrod Wallace suspended for the next two games Boyd will be expected to live up to his high-profile recruitment.
"Reiny gets out and brings me onto that ball and I think that's what I need as a front-rower," Boyd said.
"I'm not as quick as a lot of them but once I can wind up and get going it's a hell of a lot easier.
"He gets out really well and he holds up those markers and gives me a chance to stop that man from chopping me from the inside.
"The first couple of weeks I was coming onto the ball too flat and not winding up enough and not using my size and getting those big carries for the team."
But while their on-field partnership is full of positivity, their habits as roommates threaten to tear them apart.
"He’s just got to watch the room service late at night, that’s the only problem," Rein warns.
"You’d think being a farmer he’d get up nice and early but it’s pretty hard to get him out of bed sometimes."
When asked to sum up his roomie, Boyd responded: "He's a liar by the sounds of things!
"Obviously being a dad and a farmer I'm up at 6 o'clock every day. I'm the one waiting for Reiny to wake up to go for breakfast. Being a loyal roomie I wait for him but he doesn't get up until 8.30.
"I think it's that surfer mentality, real laidback and relaxed.
"And he has night terrors. He literally has night terrors. You'll be there in the middle of the night and you think someone's trying to rob you or hold you up, he's carrying on and swearing. It's pretty full-on actually."
