HIP (High Impact Polystyrene)

I have an Onefinity wood worker with the Makita router. I am about to build some stencils out of .060 HIP. I will be using an 1/16", ‘O’ single flute (Amana 51441) bit with one pass. Can anybody tell me if I should be using climb or conventional with this? As well if possible the spindle RPM speed and feed?

thanks for any help
