Spoke Size / Spoke Length Database - What size spokes do I need?

Front: Phil Wood High flange, Mavic open pro, 32h, X3 = 290mm
Rear: Phil wood HF double sided, Mavic open pro, 32h, X3 = 290mm

Please feel free to join in and and your own, or leave a slightly useful thread for anyone building the exact same thing I did.

This is according to the DT calculator.

Phil Wood HF / Mavic Open Pro / 32h / 3x / 12 mm nipples = 292mm front, 291mm rear

(with DT Champion 2.0 PG spokes)

edit: I've assumed a spoke hole diameter of 2mm in both cases, is this correct for Goldtec / Phil? Can't seem to find this information anywhere.

Now using the Edd calc selecting Phil Wood, front and Phil Wood, rear I get 292.1mm and 291.6mm for front and rear respectively.

Is it time to bit the bullet (and ignore specs by gizmond above) and just buy a box of 292mm spokes for both wheels and be done with it? They come with 12mm nipples.
