So as to not completely highjack this thread, I'll take my posts about tire selection to the other.
Suffice to say, I am looking at which Conti's to get... likely the 4000s, maybe the 4-Season. Here's a test report, albeit posted by Conti (biased somehow?):

UPDATE:
Changed my mind about using Michelin Pro3 on our tandem. Went with the Conti 4-Season 25mm instead at an addnl $10/ea tire ($42/ea), but the feedback from ya'll and my further research seems to indicate these will be a good compromise btwn ride performance, durability and safety. On the plus side it seems to be a slightly beefier version of the 4000, but the downside is that comes with a bit more rolling resistence.
Tks.
