I have been skiing on Indigo skis over the last couple of years (Salomon prior to that). I skied on Indigo Slalom skis(165cm), AllMountain (172cm) and Twintips (185cm). I can't say a bad word about them, in fact, they rock! each of them is great in their element. they are very responsive, with great directional stability (ie they're not all over the place). Twintips are great in soft snow, clearly awesome powder ski. The twintips are on a softer side, so don't know how they would handle hard pack and ice (but then again, why not use the slaloms or allmountain for it?).
Also, they look great, so people chat you up trying to figure out where you got the pair. they're not the cheapest skis i have ever seen, but if you can afford a pair (or two
) go for it, you won't regret it!
