I love my u510 4 iron, favorite club in my bag. From the first swing in my fitting it knocked out my C16 Project x 5.5 4 iron for summer and Titleist 21 hybrid in the winter. Would love a 505 5 iron in the same Hzrdus 6.0 stock shafts ( like Harmon had winning the Open )! There is no way to go to a fitting to try anything close to this setup with the 505, 200 or 350. Please let me special order or make the 505 5 iron available as I believe the market opportunity is great for this offering. You will sell a lot of these to people like me that have gone through a lot hybrids with no success
