I loved the look of the Rolfs when they first turned up; the paired spokes look the bomb. I remember hearing bad stuff about them, but it was probably just speculation. The wider gap between the spokes supposedly requires a heavier rim, but IMO the rim just needs to trade lateral rigidity for vertical rigidity for paired spokes... anyway, you seem pretty happy with em.
I'd say your best bet is to lace them up and take them into the shop for tensioning, since the lacing takes a bit of time, and the high tension required in low-spoke-count wheels (say under 28h) really should be checked with a tensiometer.
Also, you don't need money to get hold of a copy of The Bicycle Wheel; the ability to download torrents should suffice, if there enough peers.
