I am having difficulty with this. I cannot turn the nipples without also twisting the spoke (which are aero bladed). Pretty sure I have the right tools for the job - Park Tool spoke wrench and clamping spoke holder. But I am a little reluctant to clamp too hard on the carbon spoke for fear of damaging it. I contacted the wheel manufacturer (Winspace) and they said they do not use Loctite or similar on the spoke threads. Any help would be most welcome. The wheel needs truing - approx 2mm (edit: exactly 3.4mm) of side to side wobble. Spoke tension meter shows no spokes are unreasonably out of tension.
