Kear was playing rugby union for London Welsh, until he moved back into the 13-man code mid-way through the 2015 season with the Broncos.
“I enjoyed my time at London Welsh and it was a really good experience,” said the 26-year-old.
“I always had a view of trying to go back to union at some stage as I’d been out of that game for so long.
“I wanted try my hand at it as I’d never played senior rugby union before let alone being full-time.
“I met some really good people there. Justin Purnell brought me in and we got along really well, but I think League is my sport.
“It’s where I made my name and I’ve been full-time for seven years now. I think the game suits me more as a physical level, it’s faster and I’m a much smaller bloke.”
Kear actually played at the stadium last year, when on trial for union outfit Cardiff Blues.
He is looking forward to playing rugby league in the famous old stadium.
“I love the Arms Park, it’ll be good to be back,” he said.
“The atmosphere there is always great. I can remember watching the likes of Iestyn Harris with the stadium being packed out and if we can get a few thousand there on Friday against France, it’ll be just as good.
“I think we’ll get a big crowd as there plenty of Super League players on each side.
“I’ve looked at the French team and they look strong but then you look at our team and we’re just as strong.
“If we play anywhere near how we did against Scotland then it’ll be a great game and we’ll have no excuses not to get the win. We’ve a strong team this year.”
