My RepG only has three types of skeinforge as the options, but I downloaded direct from slic3r the latest version and it looks like I can just use it directly to write gcode, and with TONS of options. I've sliced a tiny test part with FlashPrint at each resolution setting, as well as the same test part with slic3r at a few different layer settings, going to try each one and see how the test part comes out, and will label each with whatever version of the gcode applied. It is just a 25mm square block with a height of 14mm and radii corners, but oddly enough FlashPrint estimated times were highest for the 'standard' setting, and actually faster for the hyper and high setting (high estimated the fastest print time)
