https://www.titleist.com/teamtitleist/team-titleist/f/club-fitting/18604/shafts-in-my-ap2-irons I am playing AP2 irons with PX 5.5. I&#39;m considering re-shafting to a light slightly more flexible shaft but wonder how it will effect the playability of my irons. en-USTelligent Community 10https://www.titleist.com/teamtitleist/thread/81889?ContentTypeID=1Thu, 08 Nov 2012 13:42:56 GMT9ab519fc-5311-4952-85cd-0a0ceffb73fb:1f3c22fa-e5cc-40e1-b5ed-e90a57f3d7beCameron D<p>Cliff,</p> <p>In some cases, the lighter the shaft you switch to, the higher the ball flight/spin can get. &nbsp;This is the case with many shafts, but not all. &nbsp;The PXi has similar characteristics (kick point/spin) to the original Project X, but is close to 10 grams lighter. &nbsp;This is a good option to consider if you like the Project X, but just want something lighter.</p> <p>Cameron</p> <p>1-888-TITLEIST&nbsp;</p><div style="clear:both;"></div>
