PORT Adelaide midfielder Tom Logan is set to become the Goldilocks of protective headwear in the AFL over the coming weeks, vowing to experiment with different helmets in the hope of finding one that's just right.

Logan became a talking point in the opening quarter of the Power's clash with North Melbourne last weekend when he ran out onto Etihad Stadium wearing a helmet for the first time.

The hard-nosed onballer, nicknamed the "new junk-yard dog" because of his uncompromising approach, first contemplated the idea of wearing a helmet in round 20 last season after being concussed for the second time in four months.

He had suffered a couple of minor concussions playing in the SANFL in previous years, and had a history of head knocks growing up, but decided against the idea, figuring he could get through the last game of the season and probably the whole of the next pre-season incident-free.

Logan figured correctly and the helmet idea was buried alongside the club's tumultuous 2010 season, but it didn’t take long for the issue to re-emerge.

Logan received two head-high hits in Port Adelaide's loss to Gold Coast in round five and despite being cleared by the club's medical staff to continue playing sat down with doctors after the game to discuss his concerns over a mounting number of head knocks.

"After the Gold Coast game I had a chat to the doctors and thought it might be smart to start thinking again about wearing a helmet," Logan said.

"I seem to get hit in the head more than other players. Whether that's because I go in head-first or am more of an in-and-under player than others I'm not sure, but I'm sick and tired of getting hit in the head.

"I talked about it with the doctors and they left the decision up to me."

Logan's experiment with protective helmet No.1 lasted only a quarter.

The helmet, which had to be ordered in, had only arrived at Alberton the day before the game, denying the tough 25-year-old an opportunity to test it out at training.

"Last weekend was really just trial and error. The first time I'd worn the helmet was in the warm-up before the game," he said.

"It wasn't right for me. It was more a helmet like they wear in rugby union - it wasn't really an AFL helmet.

"It blocked a lot of my hearing and [impacted] my awareness out on the field.

"It's important I can hear out there and know what's going on otherwise it's probably just as dangerous wearing a helmet as it is not wearing one, so at quarter time I decided it wasn't working for me and took it off."

The negative experience hasn't put Logan off the idea of wearing a helmet.

The former Brisbane Lions rookie is waiting on the delivery of another different sort of headgear, which he hopes will better suit his needs.

"We're going to go through a few more helmets," he said.

"We haven’t actually come across an AFL helmet as yet, ones like Shaun Hart used to wear or Nathan Burke, who I remember wore one back when I was a kid.

"I'm still open to the idea of trying one out and if I find one I like I'll be keen to wear it."

Concussion has been a hot topic of debate this season, following claims by ex-Melbourne defender Daniel Bell and former Fremantle utility Daniel Gilmore that his during their playing days had contributed to serious long-term health issues.

A helmet suited to Australian Football and proven to protect the wearer from concussion is yet to be designed, but Logan said he was willing to try anything that might help protect his head.

"The head is obviously a very important part of the body and I don't want to be making any mistakes with it," he said.

"The helmets protect you somewhat, but if you get a hard knock you're still going to get knocked out, so there's still a chance of being hurt. I'm not sure if they [helmets] work or not, but I'm keen to try and find out."
