Pros: Versatility, stability, edge hold, relatively low swing weight, stiffness
Cons: Not well suited to low speed or short radius turns
ON3P was kind enough to ship a few pairs of their 2011-12 lineup for me (and family and friends) to play with over the Fourth of July weekend.
I have a couple of ski buddies who are big ex-racers and charge everything, all the time, but have never skied a rockered ski. I figured they'd have a blast on the 191 ON3P Wrenegades (mounted with Marker Jester demos, and positioned at the recommended midsole), and I was right. They each got nearly a full day on the Wrens, taking them around pretty much everything that you could experience over the weekend, from soft to groomed to bumps. Both raved about how playful yet powerful they were, and about their versatility, particularly for a wider ski.
I only got a few runs in on the Wrens, because I was unable to pry them from my friends for most of the weekend. But on those runs, my reaction was that they were sort of a combination between my 190 DPS Wailer 112RPs and my 190 Moment Rubies. I guess that's not surprising, given their dimensions and camber, but since those are the two pairs of skis that were my daily drivers of choice for the past two seasons (10-11 and 09-10 respectively), that's a serious compliment. I tend to like long skis with long turn radii, so these were right up my alley.
Bottom line: These would be excellent daily drivers for an aggressive advanced to expert western skier, particularly in the maritime climates of the Sierra Nevada and Pacific Northwest. I would complement them with a pair of carvers for the hardest days. Although I didn't get a chance to try them in powder, their characteristics and my experiences with similar skis suggests that they would give up little in float to a dedicated reverse camber and sidecut powder ski, while gaining greatly in versatility.
As I was packing them up to ship them back, I was again impressed by build quality. I'm not sure where I stand on printed vs black bases, but leaving that aside, they appeared to be up there with the best-built boutique skis I've seen, including DPS and Praxis.
