The Revolutions on the NDS are more of an experiment for myself but will likely just continue using DT Comps on both sides in the future. After all, apart from the ride, it's the robustness of a wheelset like this that is its appeal, and so I figure if there hasn't been a problem with spokes before (and there hasn't) then why change. And I just like the symmetry of a 3x pattern on both sides of a wheelset like this.
The Rev's being 1.5 vs the 1.8 mid section of the Comp's would give around .004-5 thousandths difference in elongation under tension... more of less. IMO the weight savings would be the only reason for the chg.
I've used no DT Swiss spokes to date... Sapim's here so far. As I believe I noted earlier... my building is for personal use to date only... some of those wheels go out on bikes I've moved. My goal is learning all I can per practical knowledge of wheel building... then refining the wheels I build.. less weight per given strength/durability.
The theory behind wheel building is interesting.. but as I've read more than once online... theory and the reality of that outcome can/does vary. Rider weight... riding style.. the roads.. means a wide range of conditions to challenge one's "wheels".
