first off, all skis are 'flexy', just depends on how strong and/or heavy you are. second, Volkl makes an incredible ski, theyre bombproof and ski the best for my style of riding. i dont know how stiff or soft the expressions are, so i'd reccomend just going out and demoing a pair, thats the best way to decide. but if you like soft, the 1260s, fujatives, or scratch.
