Thanks for the interesting and contrasting comments...
This is on a Kinlin XR-300 rim and Formula hub, built 2x...I'll pull the rim strip and check how far up the nipple the spokes come....I'm suspicious they are not quite to the screwdriver flats....On the front that I built up last night, the spokes protrude slightly, and I'm not yet fully tensioned there. Might be able to trade some of the fronts for the DS on the rear.
I am using a tensiometer....pretty high on the drive side...average of 130...but substantially lower on the NDS....70 or so....any higher and the dishing goes off.
