adjustable bore sizes (as paint will swell). Used with Freak.
High quality, always breaks, bright fill, relatively cheap.
Could use more colors.
I can get a case of Proto Darts (orange shell/orange fill) at my local shop for $39.95. I would still pay more for it though, it's some high quality stuff! I've used it in my spyder with ACS and my new Ion. I was suprised to see that the Spyder anti-chop bolt worked with the proto paint, I thought it would have been to brittle.
In the Ion, the paint is consistent and always always always breaks. They are durable and reliable, as well as cheap. However, your choices are limited to orange. This paint will swell in the heat, but just swap bores and keep on goin! It will still work great in single-size barrels.
Great paint! Quality vs. price, it's all I buy now.
