Spoke Length question / round up or down?

[vibiker]

I am looking to try Sapim spokes for a wheel build. The probem is that Sapim only has spokes in even lengths. And of course I need odd length.:rolleyes:

Is it best to round up and get the next longest spoke or round down and get the shorter spoke?
If I go long, will there be enough thread for the nipple?

Thanks

1mm either way is not a big deal.
