This stuff is a bit pricey, but whats an extra 5 bucks? A drink at the bar? It's worth the money for this stuff, and it's especially good in pilot markers. (I don't even have the Big masterpiece, (yet)), but I've used this ink with pilot, in a 'tagstarr' and in a pen mop. No streaks or bullsh*t, just pure black lines. It's probably great in that big marker, but that thing is just out of control...
In my experience these get clogged quicker than Gray and Black Dots, but creates super clean thin lines. Just keep cleaning the valve as you work and you'll be gravy. Details and touch-ups, I don't use 'em for outlines, little too thin. Fun cap to work with. Cop a pack and give 'em a shot.
If you do handstyles or tag with spray instead of mops/markers, this is a must-have cap. You can twist the nozzle around to change the angle of the lines - I keep mine at about 45 degrees or horizontal - and get creative with your handstyle! Cop it.
I don't use fat caps a whole lot, and when I do it's usually an Orange Dot, but for bombing mission and flaring handstyles, this one is the way to go. Doesn't give viciously (word?) big lines like the Silver/Pink Dots or 49er Caps but empties a can with some ill fatties with ease. Must have for every bomber on the street and for writers who are doing XL pieces.
After the Orange Dot, this is my favorite fat cap. It doesn't get much easier than this thing, great for filling in on pieces because it doesn't create lines so big that you "color outside the lines," but fills in thick and even. Also a great capfor throwies. A must have for every writer, no doubt.
This isn't my favorite skinny cap, but on a low pressur paint, it creates some really nice thin lines. It works especially well on Ironlak for detail work. Thin-medium lines on Hardcore. Worth giving a shot - I think this is a preference cap.
