I got the chainline on the RD cranks to be acceptable (not perfect) by putting the chainring on the inside of the spider with a 103mm BB. The difference between the outside of the spider and the inside of the spider is, however, more than the required 3mm, so it's a small overcompensation, but within acceptable tolerances. If I get a chance to pick up a BB with a 107mm spindle for cheap, I might try it. That would move the chainline 2mm to the right, which, I suspect would bring it closer to perfection. This is mostly because, as a matter of principle, I want a perfect chainline, not just an acceptable/safe one. As it currently is set up (103mm BB, Chainring on the inside), it's fine.
edit: I also like the RD's a lot. They're reasonably light (not weight weenie light, but light enough), tough enough and they have a very comfortable (for me) Q factor.
