Delayed Hip Action For Those "Tweeners"

[cometgolfer]

I've been playing well over the last month (shooting a 66 and 68along the way) as more Machine concepts have become clear(hinging and rhythm in particular). One thing I have been struggling a bit with is how I handle those "tweener yardages" when I can't hit my stock shot. This has been particularly true with the shorter irons and I'm just not getting it close enough from 140 and in.

I'm a swinger and seem to have a difficult time regulating thrust for these types of shots. Has anyone tried using delayed hip action to preset backswing length as a distance control technique? Any advice or things to look out for when doing this? I messed around with it at the range this evening with encouraging results.
