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 Feb. 14-20, featuring Kris Blanks, Karin Sjodin, Zach Johnson and more:
@ANNIKA59 Kai teaching the girls about core strength and connecting the upper and lower body during the swing. http://plixi.com/p/78848394

@cobragolf New Matrix Radix 8X RT @CobraPumaFL @cobragolf @ianjamespoulter what shaft are you using for his best trajectory?

@CallawayGolf The wait is over. Callaway’s new line of RAZR products are available at retail today! What new RAZR products are you going to try?
@odysseygolf DART is now available. Are you going to try the latest putter technology?
@IanJamesPoulter http://twitvid.com/LG2UA  - Video of me regripping my White cobra ZL driver 5 layers under right hand & 2 under left. Enjoy
@IanJamesPoulter By having 5 layers under the right hand & 2 under the left it evens out the taper a little bit, it feels much more comfortable in my hands
@IanJamesPoulter The rest of my irons will get regripped tomorrow i want fresh grips on for the next run of tournaments.
@IanJamesPoulter Slightly thickening the grips has no relevance to ball flight or shape at all, its purely to even out the taper.
@IanJamesPoulter We have some new toys in testing @cobragolf busy on the range. #TwitPict http://twitpic.com/40s3rp 
@cobragolf I guess when a grown man sweet talks his driver he's still happy w/ performance... #whiteZL #truelove #TwitPict http://twitpic.com/40u4ug

@peterjkostis Twitter Tip. The shape of your swing must match the lie angle of the club you r using.More upright for wedges and more around for the driver

@peterjkostis Twitter tip.Good putting starts & ends with speed control. Pick a speed to read the putt then you must hit it that speed or read is no good!
