There is slush with the consistency similar to a snow cone which I think is incredibly fun to ski. Then there is that heavy, wet, sometimes almost gooey stuff that can sometimes result in deceleration, hyper extension or torque type knee injuries or sometimes back strain type injuries.
Having good carving technique can help in heavy, wet snow conditions as well as most other skiing situations but I'm not sure that it is a magic bullet for all spring snow conditions. Often very helpful is rubbing in a high flouro wet snow wax like Dominator Race/Wet Snow Butter or similar waxes produced by other wax brands. The right wax can often make those conditions much more manageable. If you expect to encounter heavy, wet snow, you might also want to take your skis to your local shop to have them grind in a coarser structure appropriate to spring skiing which will help reduce suction or you can do it yourself with the right tools and know-how. The high flouro and stonegrind options are kind of pricey but can produce significant improvements.
As far as equipment, I leave that to personal preference. I find that a stiffer SL or GS type ski works best for me. I've never had a knee injury in spring snow but know people who have. Properly prepared you can have a lot of fun spring skiing. Just don't forget your sunscreen.
