I have a pair of 2013 Rossi S3s. Currently, they are my only ski, and I'm looking to expand my quiver. Would anybody else that has ridden them be able to give me a description of their flex? They seem pretty stiff to me, but I don't have a point of reference. Gonna be picking up a pair of Jskis Whipits, and a pair of pow skis (undecided), and would like to know the flex of the S3 so I can compare it to the skis I want.
