I've been using the Renoun endurance 98s for the last couple of months. I've had ~10 resort days and ~15 BC days on it. I can't imagine a better mid-fat ski for 50/50 use. It's light and so easy to pivot, while also being crazy stable when letting them run and in crud(it's as stable as my Brahmas, though with less pop). It's a crazy ski, it defies the usual tradeoff between weight and stability. It's not a perfect ski, the HDT that gives you that crazy speed dependent feel also inhibits rebound ('pop', 'energy'). It feels very different. I still do masters racing, at high speeds I can pressure the Renouns more than my GS ski. I can still remember the first time I tried to overpower it, I could not believe how stiff it was, I simply couldn't blow it out. With similar pressure my GS ski would catapult me at the end of the turn, the Renoun barely rebounds at all. That's not necessarily a bad thing (and in some circumstances I think its advantageous, i.e. moguls), but it's unlike anything I've felt before so it takes some adjustment.
