dashing the lines make the plot looks so bad

for example, 

Show[Graphics[{AbsoluteDashing[{10, 5}], Line[{{0, 1},
{1, 0}}],  Thickness[0.02], AbsoluteDashing[{5, 10}],
Line[{{0, 0}, {1, 1}}]}]];

making it thicker shows the problem even more
severely. 

but it appears to me there is some kinda pattern... i
just don't know what it is. 

below shows this pattern (i think) of dashes showing
up rotated every so often. 



Needs["Graphics`Legend`"]; 
Needs["Graphics`Colors`"]; 
<< Graphics`Graphics`

Plot[{Sin[x], Cos[x]}, {x, 0, 5Pi}, PlotStyle -> {Red,
{Blue, Thickness[0.02] , AbsoluteDashing[{1, 10}]}},
LegendLabel -> "this stuff \nlooks weird",  PlotLegend
-> {"Sin", "Cos"}, LegendPosition -> {1.1, -.25},
LegendShadow -> {0, 0}, ImageSize ->  500]; 

maybe if we get rid of the rotations, then the dashing
will improve in appearance. so... is that possible? 

thanks in advance for any insights 

sean
