For many folks, these are both standout skis. The Enforcer was a top, maybe the top, around 100 ski I tried last year, very versatile, great turn. I even skied it on a 2 1/2 ft. fresh powder windfall day, and while I might prefer a fatter ski for that, the Enforcer was great, wonderful in deep. Its one weakness, for me, was edgehold on really hardpacked, steep terrain. But in the West, it holds an edge well in most conditions. And it turns in an incredibly smooth way; a standout.
I've only demoed the Volkl 100eight on a 2-3" fresh, early season day, when new corduroy or that 2" dusting were on most slopes. So I haven't had a chance to really find out what the 100eight can do, probably. For me, so far, it's not a ski I'd use on old snow or small bit of fresh days, from what I could tell from that demo. It held an edge and carved well, very quick. With a characteristic round Volkl turn. But it does not have the solid, damp, do everything feel of, say, the Gotama 108 - the ski it maybe will replace eventually? Not sure.
This ski seemed to be for those who like a good Volkl carver, and a light, quick, "light on your feet" type of ski also.
But to give it a second chance, the real test(s) of the 100eight for me will be how it does in deeper snow, and on more varied slopes. I hope to try this mid-season this year, another go with a ski lots of people really loved.
It's a Volkl, afterall.
