I won't hike or hunt steep terrain without crampons anymore, as my broken leg on Kodiak likely could have been avoided if I had been wearing mine instead of leaving them in my pack. I used Hillsound Trail Crampons http://www.hillsound.com/2products/trail_crampon.php for all of last season, and was very happy with them. Although they don't have a fixed footplate, I never had any trouble with them sliding-- I bet the shank in my mountaineering boots helped prevent it though, so not sure they would do as well on boots with a lot of twist in the sole. The Hillsounds are also super easy to take on and off, as they use stretch rubber and Velcro to make them easily adjustable.
We Also have a couple sets of stubai fixed footplate crampons, and they work great...but a are lot heavier and more of hassle to don and doff. Probably overkill unless you are ice climbing. For most sheep and goat hunts I think the Hillsounds are more than adequate.
Becca, You don't wanna do any glissading or grass sliding wile wearing crampon's.. They can bite into the terrain and send you tumbling and or break an ankle.. Best to do what you tried to do with you're trekking poles (self arrest) and slow down or stop..
My bad Becca... I read you're post wrong..I was assuming you were thinking you could have controlled the speed of your slide if you had been wearing them.. That's what I get for assuming
