Replying to Edges on new skis...detuning?

aight so in the past ive just detuned any new skis i get underfoot after each of the first three or 4 days skiing... and it worked great for the park but i totally lost my edge hold on our icy east slopes. i dont want to just leave them tho cause i ski park real hard and they get so many burrs and shit im falling pretty hard when i catch. so obviously ill just have to compromise but what does everyone else do with this?
