Replying to On3p Filthy Rich vs Line Chronic

I've been pulling my hair out trying to figure out what skis I should look into for this season. I'm definitely into the tip/tail rocker of both the chronic and fr and I've read awesome things about both. I'm 20yo, 6'1", and about 185 lbs. I ski about equal park and all mountain, but when I'm cruising the mountain, I want a ski that is going to hold up at like 50 mph. I don't want the skis to chatter like crazy at speed. I currently ride 176 Suspects. Yeah I know everybody hates on them but the fact they can fly down the hill and hold a nasty edge is one thing I really like about them. Now it's okay if the skis I pick can't quite go that fast, but I still want them to hold up. Any differences you guys know between the skis would be a huge help. Thanks guys
