well what're u doing? mostly park, half and half, mostly all-mountain, east coast or west coast?
If you're on the east coast, get the chronic or the PE. The chronics are lighter, but probably about the same stiffness as the PE. I demo'd the PE's last year, and I liked them, but I knew they'd take a little getting used to, so before I decided, i demo'd the chronics. I immediately fell in love with them. So it's more going to be personal preference. Nothing anyone on here can tell you will outweigh first hand experience.
if you're in the west tho, and see powder a lot, i'd say definately get the chronic wides over the PE's.
