^ Nice (though I tend to use the spotted ones with suits only). I think those are both n. 3 (crunchy and loose). Note how in n. 4 (crunchy and tight) the knots are tighter and slightly more on a zig-zag rather than a straight grid. One can see that quite clearly in my comparison shot of the two bicoloured ones above.
