If you take advantage of the 14-day trial of GTD Connect, you can check out a video interview with Dena, one of the Connect members. She uses the ARC system (although she coyly doesn't call it by name!).

I use Filofax, but have used the Circa in the past. You might also look on the DavidCo Web site - there may be a whitepaper on how to set up a paper planner - I can't remember if that's accessible outside of Connect or not...
