.689, because ProCaps actually makes the right sized paint.
I bought a bag of Bronze instead of my usual Blaze, and it was three dollars cheaper. I'm very impressed, ProCaps has done it again. ( ProCaps makes DraXxuS, Xball, Diablo. They're an awesome paint manufacturer. )
This paint has a very good shell, breaks quite easily, however not so easily that it will burst in a lower end marker, as it was fine through my friend's Spyder. The shape is also impressive, I found few dimples, and it was all very round. It is a perfect .689. The fill is also very good, makes a big splatter, but not quite the massive splatter from Blaze. It's very bright, and in good colors.
ProCaps makes for a pretty bag too, which, although unnessceray, is a nice touch. The bag does keep the paint in awesome condition, which is more than I can say for Evil.
Excellent paint. Slightly cheaper than Blaze, but only a dollar more than whitebox at my store, and it blows whitebox away. If you needed something of a higher quality, use Blaze. ProCaps is simply my favorite paint manufacturer, hands down.
