I don't really do it at all. I'll climb one way or the other, unless it's crane work or (I can only imagine) an extended, epic West Coast Conifer exploration. It really all depends on the type of situation one encounters, or ultimately, how often you'd need to relocate your Tie In Point/Primary Support Point....Do y'all find yourself switching between techniques (SRT and DdRT) often?
You can prune and remove all in SRWP systems without changeover. If you're working off a crane, or alternating systems up a larger conifer, you'd probably want the convenience of DdRT retrieval/advancement.
In a prune, the capabilities provided by simple false redirects are incredible, whether retrievable or not. These options are really what makes SRWP shine in my opinion. Without them, things may actually be more difficult.
Best thing is to know the options, then approach the work with the best kit for the task.
