specbill has direct relevant experience, but I'm interested in your need/desire for a front disc. Is this an off road tandem or are you located in a locale featuring a lot of climbing? There are numerous threads on brakes and teams climbing/descending with dual calipers, dual v-brakes, front caliper/v-brake, etc. Just about every combination depending on riding style and team weight. The key for the vast majority of teams not having a drum brake is managing rim and/or disc heat which is definitely a riding style issue.
