I, on the other hand, am a huge fan of glissading. Last June I glissaded down the chute next to the 99 switchbacks in soft, slow snow and used my poles when I needed to check my speed (which never got very fast and certainly never out of control in the soft slush). What I felt more dangerous was post-holing through the snow back to the trail - the occasional collapse and getting a leg/ankle caught in the boulders below.
Two weekends ago I glissaded down one of the chutes of San G (again, in soft, sticky slush) and didn't need to check my speed at all - I wanted to go faster!
And just this past weekend I glissaded down Tyndall where I went over a couple icy patches, but with my piolet I stayed in complete control. Snow conditions were great for the glissade.
I didn't bother glissading down Shepherd Pass due to rocks and thin snow cover, instead I made solid plunge steps.
It's all about individual risk tolerance and evaluating the conditions.
