Many prominent golf companies and pro tour players 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 Jan. 3-9, featuring Graeme McDowell, Annika Sorenstam, Justin Rose and more:
@louisefriberg Off to bed now. Have a game early in the morning on west side of town!! Will try my @PingTour Anser stix tomorrow and see how they feel:)
TWEET OF THE WEEK
@AldilaGolf It's important your #golf shaft has the right length. Make sure the length matches how tall you are Click here to see more -- Aldila Golf
@taylormadegc Dustin Johnson led Hyundai with 307.9-yard driving average. Wasn't kidding when he said he's picked up yardage with his new #R11 driver.
@ZachJohnsonPGA Made it through Kapalua with 9 functioning toes! Just landed on Oahu...hoping to be able to wear closed toed shoes this week! Aloha!
@McIlroyRory Getting ready for another year on tour!! Click here to see photo 
@BeatrizRecari Winter training=Practice, practice, practice and more practice...
@mariahjorth Out hitting some balls before heading to Sweden tomorrow. Take advantage of the great weather!
@PaulAzinger Gripping club in fingers is key.Hand size can determine if grip looks strong or weak.Grip determines SWING fundamentals.NOT OTHER WAY AROUND
@JustinRose99 “@drtitleistfan: @JustinRose99 how's the r11?” Yeah, it's feeling solid! Been a very easy change. I've been comfortable off the tee this wk
@JustinRose99 “@coesign: @JustinRose99 @drtitleistfan does the color bother you?” the R11 looks awesome in white. After 10 mins you'll love the look
@Graeme_McDowell The new #Cleveland #Srixon wands!!!! Check them out. Click here to see photo 
@Graeme_McDowell Callaway gone because my contract was up and we couldn't come to an agreement. I've left a great company and gone to another great company.
@Graeme_McDowell #Cleveland #Srixon are making some fantastic equipment. The Z star ball is fantastic and the new ZTX irons are beautiful. Start of a new era
@Graeme_McDowell RT @ray_matthew @Graeme_McDowell what shafts you got in the ZTX? >> Project X 6.5 flighted Rifles.
@Graeme_McDowell RT @soflahack @Graeme_McDowell will you be gaming the driver at some point? >> Used the Cleveland Launcher today. My old FT Tour first 2 rds
@Graeme_McDowell Using the same 588 #Cleveland wedges that I used in college. They are the best. I have 47, 51 and 58 degree lofts all with standard bounce.
@Graeme_McDowell An equipment change after last year seems strange but nowadays all the manufacturers are making great stuff. #Srixon will be great for me.
@Graeme_McDowell And I'm hoping that 2010 was more about the Indian than the arrow!!!!!!!
@carlingcoffing Wow it was windy out there today!! My rusty swing is making this tough enough!
@louisefriberg Of course he is playing PING!! Click here to see photo

@ANNIKA59 Don't putt to a hole. It's all about speed. RT @JBBookworm: @ANNIKA59 : what's your best tip for learning better lag putting? Thanks!
@ANNIKA59 No, the oppsiteRT @paulwdyer: @ANNIKA59 @ladybugduffer Does a bare lie and soft green make you want to use a more lofted club and more spin?
@JustinRose99 First full round with R11 today. Performed well especially in wind! It's pretty low spin so holds its line well and good distance into wind.
@JustinRose99 Got it set up with 9deg loft and the new sole plate feature on the open setting. This helps the ball to start a little right and draw.
@JustinRose99 “@NotoriousWhips: @JustinRose99 is your R11 a TP version?” Yeah it is... Looks like you get to enjoy some pretty cool new toys too?! Lambo?
@ANNIKA59 Working on my short game. Going back to basics. That is the best way to practice in the winter/off season, which is all the time for me now
@ANNIKA59 Indoor facilitiesRT @ToddLewiSS: @ANNIKA59 Very difficult to work on my game during an upstate New York winter. How did you do it in Sweden?
@ANNIKA59 Depends on lie, how much green I have @ladybugduffer: @ANNIKA59 What club do you use to chip with from say 20 yards in and around the green?
@PGA_JohnDaly Unbelievable how my driver b4 was so good & then I hit my new R11 & I LOVE IT! Hitting it approx 15/20 yards further & the Irons are great!
