I debated the single H, but I *really* love the SSS configuration. Soooooo many tonal options. we play a lot of classic rock, but also oldies, blues, country, new rock, hard rock, you name it. I think the SSS will fit like a glove. 
In that case it's only Big Al 5 left!
If You play rock stuff, maybe single H in series/passive will be the best for that?
I switch that position (bridge H) on my reflex when playing some rock stuff, tone knob full open!
Brutal cut through when drummer and guitar player "step on gas" when rockin'!
