agreed with what j9td said. slushy conditions don't demand sharp edges-- in slush there's plenty of soft snow to bite into. it's hard/icy conditions that make you wish your edges were freshly tuned so you can bite into a snow surface that doesn't offer much to bite into
but yes what you will likely want and i highly recommend is a fresh wax job, ideally with the appropriate temperature range wax (but all weather stuff will be fine if not). spring conditions are awesome but you will want fast, freshly waxed skis so you carry your speed through snow that can be warm, sunbaked, overly slushy etc etc on a spring day. and it's not just straight up speed, a fresh wax job will make your ski more predictable and better at initiating turns, which can be a little bit of an issue in (very) slushy snow
