You'll love the Pacentis. I have a buddy who has them. CX-Ray spokes. He runs his 22mm front at 70 lbs., but he only weighs about 165. In any case, you'll be able to run lower pressures, the wheels will be more aero, you'll corner more confidently, and you'll be just a tiny bit more comfortable and faster, too.

I just built a tandem front with a 23mm X 28mm rim and CX-Ray spokes. I used a BHS C472w / XC279 Kinlin Road Rim from bikehubstore.com. You might consider one of their hubs, too. Only $57 for that rim, which built up very nicely. No logos. I'm running a 25mm PRO4 Endurance on it, which measures about 27.5mm. I run them at 110 lbs. on the tandem. Not optimally aero with that rim, but better than a 19mm rim. Our team weight is ~290.

People do run Pacentis on tandems, and many teams are running these Kinlin XC279 rims.
