Revs are definitely a little trickier to use for a first build. As said above, prepping the threads with a light lubricant will help a lot. Also keep in mind that a lot of experienced wheel builders don’t recommend using Revolutions on the drive-side of the rear wheel, since it’s under higher tension than the non-drive-side and the front because of dishing, plus it is also subjected to the force of the drivetrain in a way that the other side isn’t. This includes Gerd Schraner, the man who wrote the Art of Wheelsbuiding, which is essentially the official DT Swiss wheel building manual.
Using Comp on the drive-side and your weight savings will probably end up at around 75g (play around with DT spoke calculator and see). Not worth it in my opinion for a first build.
That said Revs hold up fine on my builds (with Comp on drive-side though), and I’m a big bastard.
