Bunkers are hazards. As such, I'll take them in all shapes, sizes, and consistencies. The more variation in the type of shot you face from one, the more difficult it is to acclimate and prepare for them all.
When I play a course, I usually hit a few practice putts to get the speed of the greens right. I rarely hit practice bunker shots, so it's a real bummer when you get into sand and it's harder, softer, deeper, or shallower than you expected. The fact you can't take a practice swing and have to judge everything by how it feels against your feet just stinks for a bad bunker player (me) stuck in one.
