You need a way of stopping the spokes twisting / winding up. I achieved this with a piece of wood and a slot cut with a hacksaw blade
There is a Sapim tool for that, but it's just a bit of plastic with slots in it. It does have the benefit of no splinters and a slot for CX (& DT New Aero, although presumably you're supposed to buy the DT spoke holder for those) on the other side.
Either they stretch more or they come up short as a few of the spokes have threaded into the nipples as far as they can go
The stretch should be the same as Lasers/DT Revs. It will be quite a bit more than Race/Comps at the same tension as the cross section is about 30% less. AFAIK, the DT spoke calculator allows for this, which is why it has a field for spoke type.
I had my first experience building with CX ray spokes. My experiences are:

Either they stretch more or they come up short as a few of the spokes have threaded into the nipples as far as they can go. As such, I have ever so slightly less tension on my DS spokes as I would like.
I would recommend you order 2mm less than your spocalc figures suggest.
