Players have reacted positively to speeding up play after the first round of the inaugural Shot Clock Masters.
Players were allowed either 40 or 50 seconds to hit the ball at the event in Vienna, Austria, or risk a one-stroke penalty if they exceeded the limit.
No penalties were given and rounds were completed around 40 minutes quicker than normal on the European Tour.
Swede Peter Hanson said he was “loving” the format and Denmark’s Soren Kjeldsen called it a “learning experience”.
The format is being tried amid ongoing concerns that a round of golf takes too long at the professional level, setting a bad example for amateurs.
There have been some attempts to speed up play, but none as serious as this week’s experiment.
Hanson said: “I think this is the way we should play golf, the way I was born and raised to play the game.
“We played the front nine in one hour, 55 minutes and managed to get in under four hours.
“It is so nice to play. You don’t overdo things, don’t think too much and everybody is ready to play.”
Kjelsen said: “You decide ‘I am not going to back off even if there is a sound or a fly or something like that’.
“I was surprised how much that helped me because in a way you are more committed, because (you are thinking) I am going to hit now, no matter what.”
Sweden’s Oscar Lengden topped the leaderboard after the first round with a six-under-par 66, with Spain’s Miguel Angel Jimenez, Hanson and Finland’s Tapio Pulkkanen a shot further back.
