Many prominent golf companies, players and PGA instructors regularly take to Twitter to talk about their equipment and other aspects of their game. Here is a round-up of some of the most interesting golf-related Twitter entries from the week of January 14-20, featuring Bob Estes, Karen Stupples, David Toms and more:

@Kstupples Just got word from @WilsonGolf that they no longer want to market to women...so they are one and done with me.
@Kstupples I accept their business strategy but I don't agree with it. It would have also been nice if they had let me know sooner rather than now
@TitleistonTour Congrats to @Titleist golf ball loyalist @BrianGayPGA on win @HumanaChallenge. First @PGATOUR player to win with 2013 Pro V1x. #1ballingolf
@ObanShafts  TWO Kiyoshi Purple SHAFTS used by Gay for the win! Congrats Brian!
@BettinardiGolf Brian Gay wins the Humana Challenge with a BB8 Proto! Congratulations to @BrianGayPGA!
@BobEstesPGA “@timthompsn : @BobEstesPGA how's the R1 feeling?” The R1 is a great driver! I played it in round one but need more time to get it just rt.
@BobEstesPGA “@KlubHo : @BobEstesPGA looking good Bob. Still playing Mcs change to R1 yet” MCs. Haven't hit RBZ irons yet. Working with R1 specs.
@pgatourshaftrep So Phil played what he said "one of my best ever rounds" Sunday at Pebble then switches shafts and hasn't sniffed a win since! #justsaying
@pgatourshaftrep We really dont know why he switched, he played PX 7.0 his whole career, won his Majors plus 40 PGA Titles and $60 million! #gofigure
@FujikuraOnTour  Fujikura was the #1 wood shaft brand at The Humana Challenge.
@FujikuraOnTour  At the Champions event this week in Hawaii Fujikura was #1 driver shaft
