Basically how big of a distance gap between clubs are willing to accept?
For the longer clubs I’m willing to accept gaps of upwards of 30 yards. However, once I get down to mid/short irons I do not like seeing gaps more than 15 yards. When I’ve tested new irons, I’ve found it quite difficult to get close enough gappings in this part of the bag. Often the difference between the 9-iron and PW will be closer to 20 yards.
