I've seen some people talk about having your 9 iron, PW, SW, and LW all the same length for a consistent address posture on full swings, especially since the standard lie angle for all 4 clubs is 64*. While this seems to make sense on paper, are there any pros who do this? Do they typically have 1/4" progression from 9 iron through LW or do they drop 1/2" from 9 iron to PW then 1/4" through SW and LW?
