The only mixed combination that seems to work well is Valoredge head + Sharpshot body, for very fast paced parties, specially those where the mob moves around somewhat frequently. Since you won't have to worry about positioning your auto, your performance increases even if the ranged skill is reduced and the time between shots increases. It does increase the melee skill, too which is great if your auto is low on acc.
For solo, there isn't any strange combination worth using. Just deploy Soulsoother/Stormwaker or Stormwaker/Stormwaker (depending on how much the mob spams enfeebles, basically), and you're set.
