I've always used snow pickets for my belays in snow, whether it be vertical or t-slot placements. In real soft snow, I've always had trouble getting anything real good with a t-slot anchor. Are the self diving flukes better for belays in these conditions? Or at least quicker than building endless t-slots? They don't appear to be as versatile in harder snow/ice but it might be worth picking one up for the days I plan on wallowing around in sugar snow.
Thanks for any insight.
