Rip a cupped board...best/safest way?

Hi All,



I recently resawed some rosewood from a large 250x50 piece. I have got 3 boards 15mm thick x 170 wide that will eventually be 12mm thick. Not surprisingly they all cupped a bit but one has cupped about 3mm across the face of the 170 width. This is too much to re joint/thickness as it will end up too thin. This piece was always going to be ripped to 50mm wide pieces but I had planned to thickness it first. Now I want to rip it then thickness the narrower widths down to 12mm. My understanding is that this is an acceptable method as the cupping across the narrower widths will be less.



So my question...what is the best and/or safest method of doing this.



Tablesaw with hold down, blade guard installed etc....Concave side up or down?



Or Bandsaw....same question...Concave side up or down?



Any other method? Ryoba saw maybe?



Thanks in advance :)
