Does anyone have suggestions on putting together components for a new Co-motion? We're going to order a Co-motion Speedster Copilot. We don't compete, we just want it for long (50 mile plus) rides, and we both like to climb. Does anyone have suggestions regarding:

1) Drum vs. disc brakes? Someone told us to get a shaved drum from Tandems East. We love to climb, and have a lot of hills here in Sonoma County. We see a lot of tandems with drums; the shaved drum sounds like a good option, to save a little weight. But how would disc brakes compare to using a drum?

2) RE climbing: Gear ratios? The Speedster comes with a 54-42-30 chainring. Someone told us to get a 53-39-28, to manage the hills around here (Sonoma County), which is similar to what I have on my Calfee single (53-39-30).

We're getting the wound up carbon fork, the Chris King headset, the suspension seatpost, and the carbon cranks. Anything else we should be thinking about?

Thanks for any suggestions.
