While not on an Ultimaker, I've had great results with XSTRAND GF30-PA6 and 3DXTECH PA6-GF30 used in conjunction with Taulman SAC1060 support material (dual extruder machines). SAC1060 is specifically formulated for use with Nylon materials, serving as a breakaway support material - I prefer using it over soluble support materials like BVOH (HydroFill, etc), prints come out much nicer.
Glue stick works well for glass filled nylons.
