I literally had to look at it 4 times to read 'Mavrik' (in fact I just clicked back on it, because I thought it said 'marik') Solid color will definitely be easier for certain applications (such as embroidering which 1984 already mentioned.) No matter what, 'international' being splotchy was very difficult to read because the splotches were proportionally larger. International, IMHO should definitely be solid.
I like to beat up pacifists, because they don't fight back ...
I agree soild is the key and it's better for those people that can't see to good. But if your going to print it on fabric and want to still use the white spots, then just use a few of them but not too much.
