Selecting spoke lengths I'm planning to build a new wheel, using a Velocity Synergy OC (asymmetric) rim. When I calculate spoke lengths using the Edd spoke length calculator I get these lengths:

Drive Side: 293.9 mm

Non-drive Side: 294.7 mm

So, the drive side seems easy, I'll use a 294 mm spoke. But what about the non-drive side, would it be better to round up to 296 mm or would 294 mm work? How do you decide when it is better to be a bit long or short?
I would round to 294, since that would keep difference from theoretical less than 1 mm, and as bonus left and right would be of same length which means you have to stock only one size for replacements.
