Do golf pros use same clubs from tounament to tournament?

Answer 1

Generally the pros appear to keep their clubs for a good time. They would usually find a driver and fairway woods that suits them and keep these for a while, they would also keep their irons for a while as well but would occasionally check them to make sure the loft and lies are correct. They would change their irons if the manufacturer brings out a new range, and also if the grooves get worn down. With the wedges, pros would change them quite often to ensure the grooves are always sharp so they can get plenty of spin and keep control over the ball. They would usually keep their putter for a couple of years, Tiger Woods is an example of this, they do this so they are not getting readjusted to a new one ever so often.

Answer 2

No, they can change the ball every hole if they want. They do however have to use the same brand and type for the whole round.
