I have used the long SMC snow stakes and they work OK if the snow is really packed well. I use something longer for at least the 4 main anchor points though. I have also used aluminum deadmen. I have a homemade set of SST pins that are longer than the Kifaru's that work well in certain conditions.
How well stakes work is so dependant on location. In some areas, all I can get in is a Vargo Ti nail stake and at times I have tied out to large rocks when camping in southern Utah.
Like Evan said the use of skis or ski poles limites travel options unless you are moving each night.
