There is just something about a new glove. In college I developed a bit of a
habit of wearing a new glove almost every round and many people think it
is crazy as they prefer to "break" them in (which I never understood). Different strokes for different folks!
That being said not all Tour players wear a new glove every round. Jason Bohn told us we give him too many gloves and he has heaps of them stashed at his house. Kris Blanks is similar and will never change his glove mid-round if it rips or tears after a couple days of use. I believe Ben Curtis was similar in his glove use.
There are players who need a new one everyday but it is by no means all players.
