Alpha 1's are a great pair of ski. One of my friends has a pair of them and he loved them. The rocker is a bit weird to get used to at first, because the skis feel shorter than they look when you ride on them, but it's not a problem after a few days of riding.
On the other hand... I'm not sure how you can be skeptical of Chronics. I have an 09/10 pair of Line Chronics and I absolutely love them. I feel like 09/10 was the best year for the Chronic, because there was a choice of either choosing the thinner waist of the wider waist. Now, they only make the Chronic wide, which is ass if you don't like wide skis. Another thing that makes the Chronics so good is that they're extremely durable.
I've had my Chronics for 3 seasons now and I can't complain. I also ski park like 90% and trails 10%. I think the Chronics are actually a great all mountain ski, they only conditions it could perform better in is choppy snow, but then again, how often are you skiing in shitty choppy snow? Probably not a whole lot, but maybe sometimes if you're from the east coast like me haha! Only damage done to them is a few edge cracks and some top sheet chipping, but that's normal if you ski park on the same pair of skis for more than a season. I'm getting new skis next season and I was actually looking into Armada AR7s, because I feel like that's Armadas best offer for a durable ski that's similar to the flex pattern and shape of the Chronic.
