I really don't have any issue with splitting up iron sets and frankly once you get to a fairly high level, the first things to go are the hybrids.
Most of the better golfers carry the same stuff, a driver, a 3 wood, the 3 - pw iron set, a putter and 3 addition wedges. When you hit 85% of the fairways as most of the better players do, the need for hybrids goes away and the length of the 3 irons, 225 with the R11's bridge the gap to the 3 wood well. You end up with a PW that goes 120 although you can punch to 103 so your gaps are from there down.
The R11's are set to have 15 yards between each club and work well with punch shots. I know that everyone isn't a Legend and does not have the top clubs but as most of the players level up and progress to higher tiers they end up with that equipment and lose the need for a hybrid.
