Australian quick James Pattinson admits he ditched a remodelled action designed to prevent injury in order to tear apart the West Indies in the first Test in Hobart.
And he won't be changing his approach any time soon, despite the fitness headaches it may pose.
The injury-plagued Pattinson admitted his new action designed to avoid future back and hamstring problems limited him in the Hobart match - his first Test since March 2014.
It showed.
Pattinson cut a frustrated figure after a wayward 0-68 off 15 overs, at times struggling to reach 130kph.
"It was frustrating because I had changed my action and I didn't feel completely comfortable with it," Pattinson said.
"So in the second innings here (in Hobart) I just went 'stuff it really, I'm just going to go out and try and bowl like I used to bowl' and just run in and bowl fast.
"I thought if I bowl like I did in the first innings I probably won't be getting too many more games, so (I had) better change something."
Sports scientists had spent endless hours working with Pattinson on a new side-on action.
But Pattinson found form in Hobart after some simple advice from old school bowling coach Craig McDermott and captain Steve Smith - "run in, bowl fast, have fun".
It worked - Pattinson tore through the Windies' second innings with a career best 5-27.
It helped Australia crush the Windies by an innings and 212 runs within three days.
Pattinson, 25, realised the fitness implications of reverting back to his old action but believed his body could now handle it.
"I just ran in and wanted to bowl fast like I did when I first came on the scene," Pattinson said.
"It's hard because when you run in and bowl you don't want to be thinking about your action.
"I've made the change to try and stop injuries but now that I'm back in the team and I'm a bit older, hopefully my body will hold up and I can go back a little bit to where I was when I first started playing.
"Because that's when I think I'm bowling my best."
