Dick,
This is a bit OT, but one of the ideas I recently had while playing winter golf was how beneficial it is to understand important playabilities of features, and how that relates to the conditions.
While not all supers are everything, (trying not offend anyone) and most are probably extremely technically sound, I suspect many could benefit from going around thier venues, when things are rock hard, to see where maybe some minor tweaking can be best implemented, for summer.
The hard winter ground causes many more features to become playable, or "come alive". Opposed to summertime with lush grass and a soft turf, makes them disappear or are virtually non-existent. I think there might even be more benefit than just shaving a mound or a green side, there could even be areas that require the longer grass or the softer turf. Anyway, the point being I suspect they do not teach playability at super school, and since each site is specific, having standard practices in this competitive enviornment seems intellectually lazy and fiduciarily irresponsible.
Sorry for the hijack, but one of my favorite shots is to bank balls out of greenside grass swales and that can only be accomplished in the winter.
