well i've skied both ar5s and PEs and so you can trust me. my ar5s snapped on about the 20th day, but they rode alright before that. the edges also cracked really easily and by the time they snapped there were over 60 cracks in the edges. PEs are awesome alround, have a mad warranty and ski pow well too.
PEs. no question.
