I fully understand the Q-factor issue. Wide cranks are a problem for my stoker as well.

Right now I'm seriously debating the easton r90 rim vs some light-bicycle 55mm carbon clincher rims. It's the rim construction that most scared of. I don't want to get a "China carbon" part to be aero and cool to have it fail and hurt us.
Yes, it is taking a step away from what we historically think of as mainstream tandem wheels. However, so far I've heard direct Light-Bicycle feedback from two sources: mtseymour and my LBS manager/head mechanic who has built up quite a few mtn wheels with LB rims. All reports there are good. Also searching ""light bicycle" carbon road rims review" and such, I haven't found any further reason to doubt these rims. Any rim failures I've come across seem to be a result of mtn riders running with very low psi and hitting rocks (pretty much guarranteed to crack most carbon rims). Good news is that they held together quite well. Here are a couple links:

Unlike low spoke count, alloy nipple single bike wheels, our tandem disc set was built with WI CLD hubs, 32 spokes, brass nipples and nipple washers.

I would be interested is hearing of any other relevant rim failure reports... we also prefer to avoid known dangers
