Pretty much every top of the line paintball from the big name manufacturers
I shoot a 2K2, Texas Storm, Ripper and Ripper 2 Intimidators. I run a Halo or an Empire with a PMI Pure Energy Tank.
I use a Dye Ultralite or CP Kit with a 689 bore.
Consistent, variable shell, thick fill, ball.
None so far.
These are quickly becoming my favorite paint to play with. The X-Ball bronze is my favorite recball paint. It's consistent, thick shelled and flies straight and true. At my cost of less than $40 a case, it's affordable as well. I wish the colors I could get were other than white and pink fill but it's great paint. The silver and gold have progressively thinner shells but I have yet to have a break inside the marker from it. They're also affordable compared to their paint counterparts. The nice thing is that X-Ball paint uses the half-shell coloring ensuring that you know what you're shooting. Bronze is half bronze, silver half silver and gold half gold. Easy enough. Great paint. Great prices.
Top notch paint and some of the best for the price.
