I've used a pedaltrain jr. with a Pedalpower Plus for years. There were three things I didn't like - reaching over a row of pedals to get to the upper level, having to plug in (never any power outlets at the front of the stage, and it was always in the way of the legs of my mic stand. I sold the Jr. And bought two Nanos and a Volto. I'm running 7 pedals, none are digital. Now I can set my mic stand with a leg towards me for better support, put a Nano on each side, reach all the pedals easily and not worry about another cord running under my feet. I used this rig for a four hour gig and two rehearsals and still had power. I can also move pedals around and just take one Nano if that's what the gig calls for. It's a great setup. I have since bought a second Volto and mounted it under the second Nano. I didn't need the capacity, but now set up is easier. $100 is not cheap but compared to a Plus at $170 it's a great deal, as long as it lasts.
