Some suggestions: 1) The hair is a bit thick; some men have hair this thick on their chest, but then it is equally thick on the rest of the body. 2) Hair does taper (thicker at root than at tip). This is controlled by "Tip width/Root Width" parameters. 3) There is no real "curl" setting; you have to make do with "kink". Experiment with "kink scale" & "kink strength" in the 50-100 range. You can also increase "verts per hair" to increase the effectiveness of the kink settings. 4) Hair density is controlled by vertex density. Hair will be thicker where there are more polygons (which is why the muscle seams are darker). You may wish to have multiple hair groups with different hair counts depending on poly density.
