Don't switch golf ball brands during play

And even though some people don't want to believe this, switching balls mid hole is ILLEGAL unless your ball is knocked out of bounds or into a hazard i.e. water and lost. And although the rule isn't always in effect, if you start a round with a Titleist, you MUST use a Titleist for the whole round.

15-1. General A player must hole out with the ball played from the teeing ground unless the ball is lost or out of bounds or the player substitutes another ball, whether or not substitution is permitted (see 15-2). If a player plays a wrong ball, see Rule 15-3.

PART C: CONDITIONS OF THE COMPETITION Rule 33-1 provides, "The Committee must establish the conditions under which a competition is to be played." These conditions should include many matters such as method of entry, eligibility, number of rounds to be played, etc., which it is not appropriate to deal with in the Rules of Golf or this Appendix. Detailed information regarding these conditions is provided in "Decisions on the Rules of Golf" under Rule 33-1 and in "How to Conduct a Competition." However, there are a number of matters that might be covered in the Conditions of the Competition to which the Committee's attention is specifically drawn. These are: 1. Specifications of Clubs and the Ball The following conditions are recommended only for competitions involving expert players:[ . . . ] c. One Ball Condition If it is desired to prohibit changing brands and models of golf balls during a stipulated round, the following condition is recommended: "Limitation on Balls Used During Round (Note to Rule 5-1): (i) One Ball Condition During a stipulated round, the balls a player plays must be of the same brand and model as detailed by a single entry on the current List of Conforming Golf Balls. Note: If a ball of a different brand and/or model is dropped or placed, it may be lifted, without penalty, and the player must then proceed by dropping or placing a proper ball (Rule 20-6). PENALTY FOR BREACH OF CONDITION: Match play - At the conclusion of the hole at which the breach is discovered, the state of the match is adjusted by deducting one hole for each hole at which a breach occurred; maximum deduction per round - Two holes. Stroke play - Two strokes for each hole at which any breach occurred; maximum penalty per round - Four strokes. (ii) Procedure When Breach Discovered When a player discovers that he has played a ball in breach of this condition, he must abandon that ball before playing from the next teeing ground and complete the round with a proper ball; otherwise, the player is disqualified. If discovery is made during play of a hole and the player elects to substitute a proper ball before completing that hole, the player must place a proper ball on the spot where the ball played in breach of the condition lay."

Then please read the rules book rather than post here about it. It's pretty clearly written, even in the R&A; rules book I'm sure.

the official rule aside, i don't think anyone should be switching their ball! what's the point? stick with a particular ball and learn to use it !

I honestly don't see the big deal here. Yes obviously you can't use a long ball off the tee then trade it in for a pro v1 when you get near the green but besides that I see no problem in using whatever type of ball you like.

lol whatever bud. If you're ever going to play serious golf, i would recommend getting used to playing with one ball.

Just some thoughts that came to me since there are alot of people who are so picky about little rules, such as using the EXACT same type of ball for the entire round.
