I plan on asking Danny Le a few questions about this at the Distance Bash and try to learn more about it.I decided to not get htem done on my Obans because everywhere I have read, they come right from the manufacturing process pretty consistent. They are extruded vs seam welded which doesn't give you near as much variantion in bend profiled around the shaft rotation.
They pured 3 of my CT125's just as a way to show the benefit, and the results were interesting. Per the sheet, the 3 irons ( 4i, 5i, 6i )each were within 98% of true with no adjustment. Take a look below. Mind you I didn't pay for this but they did it I think as a standard way to upsell. Kind of backfired in this case as it proved my point. This below is on the 5i. From my reading, anything above a .96 you really aren't going to tell a whole lot of difference. 100 means perfectly round and straight.
