Thought I’d best ask before I make a tit of myself
The DT rim I’ve ordered comes with DT Swiss Squorx Nipples and washers included, are they any good? They look like they would be nice to build with but would require the investment in another nipple driver and wrench. The DT adjustable one plus wrench comes in at a not insubstantial £45. I’m tempted as I can imagine it would be easy building, blob of grease on driver to retain nipple and a nice even release compared to standard nipples perhaps.
What do the masses think?

Oh and do I need to adjust spoke length?

I've used them. The specialised tool for use from the outside of the rim is nice, makes building pretty easy. I borrowed the tool from my LBS.
When calculating spoke lengths, the DT site allows you to select them, so that will account for nipple/spoke length.
I've been running the wheels for a bit over 2 years now, no problems so far, knock on wood.

The washers are essential for that type of rim and mean a much stronger wheel (not going there on washers v eyelets before someone starts ). Have used normal nipples with the washers, never built using squorx. Believe can easily make own driver for them.
Just to add i am really pleased with the DTSwiss washered rims I have at the moment. They really seem to have upper their game in recent years.

I built a wheel using these, started them off using a rotor bolt (with a microscopic amount of blu-tac to hold the nipple in) used the flats on the other end of nipple to do most of the tensioning and truing.

Thats the hack I was trying to think of Rotor bolt glued into piece of dowell.
