Replying to Ways to prevent edge cracks? Best ways to get rid of your edge?

Past two years, within 3 weeks of riding on my On3p filthy riches i get many edge cracks (they warrantied my last seasons ski, got new ones at start of season) I now have 3-4 edge cracks that showed up early season and have an inch piece of my edge about to pop out. Whats the best way to de-tune park skis to avoid edge cracks. Before the first day riding I spent a solid hour with a file de-tuning but still end up with tons of edge cracks! Any advice on de-tuning? other than files?
