Ian Poulter is the latest player facing the difficult decision regarding where to play his golf next season (Ping K15 Irons).
Earlier this week, Ulsterman Rory McIlroy joined new world number one Lee Westwood in opting out of the US PGA Tour in favour of the European circuit.
But 34-year-old Poulter (Ping G15 Hybrid)is concerned the increase in the number of mandatory events on the European Tour from 12 to 13 could make it impossible to commit to playing both.
"Hopefully it won't get more difficult as I will have to make a decision myself," he said ahead of his Singapore Open title defence this week.
Poulter claims his ultimate ambition (Ping Rapture V2 Fairway Wood)is to become world number one but his immediate concern is where he plays most of his golf over the next 12 months.
"I have a house over in the States and my family is well settled over there," he continued. "But then you can't deny playing two tours is becoming increasingly difficult (Ping G15 Fairway Wood), especially with the European Tour number you have to play going up.
"It was 11 events two years ago before it went to 12 and now it's up to 13, and that's on top of having to play the mandatory 15 across the pond."
McIlroy announced this week he missed the "camaraderie" among the European players when competing in the US, as well as a desire to be closer to his girlfriend and family.
"Rory's young and he's got plenty of time to play wherever he wants," continued Poulter, currently world number 15.
"He's top ten in the world and he is going to stay top 10(Ping Rapture V2 Irons)in the world for a long time but then Lee Westwood has done exactly the same. He's now world number one so it hasn't harmed him not playing [on the PGA Tour]."
