We present a resistive Micromegas detector built with two different pillar shapes. The pillars are elongated and extend in the direction orthogonal to the readout strips. One region features pillars of 2 mm 0.2 mm with 4.8 mm pitch while in the other region the pillars extend over the full width of the detector. The larger surface of the pillars allows for a better adhesion to the readout structure and a more uniform amplification gap. Results on the detector performance for the two regions are presented. No striking performance differences between the two regions were found.
