A pad/trace line layout for a PMR writer structure having two or more writers on a slider, and a process for selecting the best of the multiple writers is disclosed. Each writer is individually probed with a spin stand test device to generate performance results including bit error rate (BER), and area density capability (ADC). After the best writer is determined, the slider is integrated in a HGA. Only the best writer is connected through trace lines to a preamp to enable functionality. At least one trace line has a plurality of arms that enable flexibility in connecting the best writer to the preamp while other arms are not connected. In some embodiments, all writers share a common W− pad that is connected to the preamp through one of two trace lines while the other trace line has one of the plurality of arms connected to the best writer.
