https://www.titleist.com/teamtitleist/team-titleist/f/club-fitting/18561/pureing-and-frequency-checking-of-graphite-shafts-for-irons-and-woods I had a club fitting at my local course on Saturday by a Titleist rep. We determined the proper swing weights and graphite shafts. He also decided that my irons needed to be bent 2 degrees flat. I forgot to ask if I ordered my clubs directly from Titleisten-USTelligent Community 10https://www.titleist.com/teamtitleist/thread/81634?ContentTypeID=1Tue, 06 Nov 2012 14:01:32 GMT9ab519fc-5311-4952-85cd-0a0ceffb73fb:4bd1f4cc-876f-4bb1-95a9-b0a8f0f78704Cameron D<p>Jerry,&nbsp;</p> <p>Puring and frequency checking isn&#39;t something that we will do. &nbsp;When the shafts are received by Titleist, they go through a thorough&nbsp;quality&nbsp;inspection to make sure the shafts meet the tolerances we have set in place.&nbsp;As far as puring goes, our Titleist Golf Club R&amp;D group has conducted testing with tour and better players to compare performance between shafts that have been PURE&#39;d and shafts that have not. &nbsp;We have never been able to see or measure any performance difference whatsoever. &nbsp;Therefore, we do not feel the PURE process adds any performance improvement or value.</p> <p>Cameron</p> <p>1-888-TITLEIST&nbsp;</p><div style="clear:both;"></div>
