For me the switches are useful. I usually keep one in series and the other two in parallel. Which one is in series varies depending on which one I want to emphasize.Those of you with toggles, do you think it was worth it? They are a pretty cheap addition, yet would be really a pain to add after the fact. The only reason I can see not to get them is for aesthetic reasons, just looks cleaner to me with the 5 knobs in an arc.
