Toronto, Canada – By Bernie McGuire
The British world number four slumped to a second round 78, putting him three-over and ensuring an early end to his tournament.
Australia's Rick Kulacz, on 12-under, holds a one-stroke lead.
"They just don't feel right and they don't feel the same, and I don't know if they've put the wrong shafts in or whatever," the Englishman told reporters.
"So I will probably get a new set sent out and reshaft the lot over the weekend to see if that does any good. They just feel like fishing rods."
A long-distance phone call to his Melbourne-based coach helped Kulacz to the top of the leaderboard.
Kulacz, 24, birdied eight of his closing 10 holes for a sizzling nine-under 63.
The Perth-born Kulacz is competing for the first time as a European Tour member after securing his playing card at last November's Qualifying School in Spain.
Kulacz, a dual winner on the Asian Tour, contacted his coach Marty Joyce after an indifferent three days of practice.
"It was the worst I was hitting the ball in months but after phoning Marty in Melbourne we managed to sort out a few things in my swing," said Kulacz.
"It was just nice to be able then to put what we discussed into practice and see the rewards, as I got that feeling back in my game while a pretty hot putter also helped today."
