I'm currently considering upgrading my irons from the original TaylorMade P790s - not because there is anything wrong with them, but they were off the rack and I likely need to have longer shafts as i'm 6'2" - I live less than an hour away from Sub 70 and am considering going in for a fitting at their HQ and then save that data and compare the numbers to other clubs like the newest P790s and Mizuno Pro 225s/JPX 923's
