Single length irons

Right now, there is one pro using them. They are neither easy to adapt (at least for me) nor simply cutting all the shafts the same length. All the heads except the 7 iron have different lofts and lies for consistent gaping. Without a lot more consumer interest or some rookies looking for a contract, "ever" may be a long time coming.

Some of the custom club makers are promoting 2-3 lengths (3-5 irons, 6-9 irons, PW through wedges a third length). Need more information on the best way to make/market them - and instructors teaching far more juniors to use them.
