Before you make a final decision, check out Cusack Effects. They build a switcher called the Pedal Board Tamer, or PBT for short. There is a 6 and 9-loop model, and the last 3 loops are stereo, but ALL loops can be upgraded to stereo. No need to waste two loops one one pedal.
Awesome bonus: A dedicated tap tempo button that has three tap tempo outputs. Tap all your pedals at once from one button.
Oh, and if you decide on it, tell them Travis told you about it on the eventide forums. I happen to work there, so I might build it for ya 😉
