I have a pair of chronics with p10 lifters on them and they have been fine for all mountain use. They are stable, but chatter alittle (not squirrly)if you go full speed down the hill. As far as the edges go, they are holding up really well. I spend 90% my time skiing at the park and 95% of that time is spent on rails and boxes. I got them last December and no cracks in the edges yet just normal wear on the under foot. Hope this helps.
