The Annex is very responsive and proved nimble off-piste as well as more than adequate on the groomers.
It took a little bit of getting used to after which it provided us with some very fun skiing, scoring consistently high for edge hold, long and short radius turns and high and low speed, although our highest score was for liveliness/responsiveness off-piste.
The K2 Annex was lots of fun and very versatile - we liked it a lot and would have no hesitation in recommending it to advanced level skiers looking for a good freeride ski.
Unfortunately the graphics are rather dull, but we can live with that.
