I'm glad you've had consistently good numbers over the years!  It has been lean and mean in most of other panhandle counties during that time.  
I hunted up around Hereford and Umbarger in Deaf Smith County for two years in a row back around 2008 - 2010.  The last year we hunted there I walked every field one day (didn't ever block) and shot one rooster all day.  It was the only time I even took my gun off safety all day and was the only bird that I even had an attempt at.  I cancelled my hunt the next day and while I was driving back home that evening told myself I wouldn't hunt pheasants again in the Texas panhandle until the numbers were at least decent.
The way it looks, I may need to head up to the panhandle in the near future, if I can find somebody to hunt on.  Do you know if they still do the hunts out around Lazbuddie through the Volunteer Fire Department there or up around Pampa?
