As some of you may know I caught a great deal on eBay for a full set of Project X 5.5's. I am putting them in my Ping G2's. They came out of Titleist AP2's. I couldn't just plug and play because the shaft prep would show terribly, so I decided to tip them to fit. I have to take 1/2" out of the tip to make the fit and finish look right. Length wise it won't be a problem but my question is how much will this stiffen the shaft flex???
