J.O pros

break easy no. bad on rails. possibly. there just a super narrow waist ski. so on rails theres not as much stability there for you. but to go as far as to say bad. i dont believe so

they dont break easy but there so buttery that they wash out alot

Mine have never washed out... and with the rails thing, no they won't break easy I used mine on rails all year and didn't have any problems.  They're just a little skinny underfoot but that's not that big of a deal

ummm the wideness(or lack there of) of the ski has no effect on rails, the wide ski makes a bigger platform so balacnce is easier but u could just as easily develop ur own balance skills and it dosent matter. as for breaking easy, i delamed a pair right underfoot cause i hit the kink on an absoltuely huge disaster when it was -30 out, it bent up the edge and broke the seal on the cap, it was only delamed for like 4 inches and i skied them for the rest of the season (jan-mar) and it didnt spread. i turned those into rail skis and they were fine. no problems. so unless u do something truly rediculous like i did then it will be fine.

except not?
