Dont know if this is an architecture question per se or a maintenance issue but I was wondering to day should bunkers be consistent in terms of the sand. My home course is fairly inconsistent, some with very little some with lots of fluffy stuff. It definitley make sit more interesting!
Absolutely not.
The hazard of being in the hazard is not the difficulty of the lie, but the unpredictability of the lie.
What bunkers/sand add to the mix is uncertainty in the assessment of the shot ahead. Consider the following situation:
200 yards out from a green defending by bunkers on the left and right. Under consistent sand conditions, the golfer is able to accurately assess the risk - simply, the golfer is able to determine the exact types of lies found with the various mishits. A reasonably good bunker player can prepare better and actually dunk it in the bunker in the correct situation.
Take away the certainty and suddenly bunkers become far more in the "wild card" category in terms of difficulty. You could get a great, manageable lie, or you could get a lie where the ball is barely hittable. This ultimately leads to a few things. First, the judicious use of bunkers by the golf architect and more reliance on the land to provide a balance of hazard and reward. Second, a serious application of strategy through the green as the player off the tee must mind the areas that are "prepared" to be uncertain. Imagine if said green had bunkers situated such that play from the left was a far safer option then play from the right - suddenly, the tee shot is vying for a position in the fairway to gain certainty in the approach.
