1. An integrated lead head suspension flexure having a plurality of regions including a tail and a gimbal, including:

  • first trace sections having a first structural configuration on a first region of the flexure, wherein the first trace sections have a first structural configuration from the set including interleaved traces, stacked traces and ground plane traces;

    second trace sections having a second structural configuration different than the first configuration on a second region of the flexure, the second trace sections electrically connected to the first trace sections and wherein the second trace sections have a second structural configuration from the set including interleaved traces, stacked traces and ground plane traces;

    one or more transition structures electrically connecting the first trace sections to the second trace sections;

    wherein at least one of the first and second trace sections include interleaved traces; and

    the transition structure to the interleaved traces includes a pair of plated conductive legs extending over an insulating layer edge.
