Graeme McDowell is in no doubt a successful defence of his Barclays Scottish Open title at Loch Lomond this week will hurt his chances for the Open at Turnberry.
A year ago the Ulsterman went from one to the other and led after the opening round at Birkdale, but ended up in a tie for 19th.
"There's no way round it, this is not ideal preparation," said McDowell.
"I've always played Loch Lomond before the Open but you couldn't get two more different styles of golf. This is soft, thick meadow grass.
"I got off to a good start at Birkdale but when it started blowing there on Saturday I just felt like I ran out of steam a little bit.
"Any time I've ever won it's a massive high and it takes you a little bit of time to come down from that.
"I think you're always learning from those experiences. I'm always a guy that, when you see players win back-to-back weeks, I think, 'how can they do that?'
"They're always good problems to have, reacting to wins, but I'm trying to do that better and better all the time."
McDowell played Turnberry for a second time on Monday, and commented: "It's got some of the heaviest links rough I've ever seen.
"If you miss it in the wrong place you might want to bring a couple of golf balls with you. I certainly lost a couple.
"Right of the 17th green I've never seen rough as thick in all my life. You've got to know which you can miss it on and which you can't."
Ernie Els, winner in 2000 and 2003 and runner-up to Tiger Woods in The Open after the first of those, does not believe that this week can have a detrimental effect on chances for next week.
"It's definitely different, but competitive golf is good preparation and it seems like players playing well take it into next week," he said.
"I've not had a great year, but this is a nice time of year for me and I'm really looking forward to it. My record will help me hopefully."
