a minor suggestion if i may

lovely collection of parts you guys have there, for the front brake though it just needs to be a slight bit older than M737 to match the other bits. M730 low profile canti in black would be very nice...silver also. and if possible....a slightly older syncros seatpost...the one with the bigger vertical writing.
brass nipples i reckon....they are much easier to live with and work on when you need to true the wheel. a bit stronger also. use nice butted spokes for weight saving and feel. two cross front, two cross non drive rear, three cross drive rear
