I want to buy my wife the Rossignol S3. She's 5'4" weight 125 Intermediate +. Use for powder on snow days. What size would be best 159 or 169. Currently skiis a 154 Vokol. Also good choice of binding?
Im about the exact same size, but an advanced skier.
If your wife is happy on the 154cm Volkl, I would recommend going with the 159cm Rossi. 169 may be a bit more than she is ready to handle when initiating turns.
I'm a 5'4" advanced skier. I ski a 160cm Rossi and I really appreciate the shorter length. It makes for quicker turns in tight trees. The shorter the ski, the easier the maneuverability. For an intermediate at my height I would not recommend anything longer than a 160cm.
