As you might expect with its long and convoluted name the K2 Potion 74 XTi ERC 11 is a pretty technical ski, with features that include 'speed rocker' technology and 'speed RoX technology', the latter using an X-shaped carbon support that sits behind the nose and the tail to aid torsional stiffness but also maintain the responsiveness of the ski.
We really enjoyed this ski, finding it responsive and easy to turn but also well able to hold its own when pushed.
The Potion had especially good edge hold on ice and steeps, and felt generally stable in most piste conditions.
This would be great for a progressive skier who wants to spend the majority of their time on piste and likes a bit of speed.
The smokey graphics didn't seem that popular with everyone but we don't actually mind the look.
