I struggled and struggled finding paint that would work with my Tippmann markers. Tons of barrel breaks just left me frustrated as I am just wasting money when that happens. Quite a few months ago I tried Proball and I have been using it ever since.
I NEVER break balls in my barrel, They break on target all the time.
Yesterday I was in an event that was field paint only. We had to use Chronic. Man barrel break after barrel break. I was so pissed. Halfway through the day the event organizer ran out of paint so they had to go to their store and get more. They brought up a trailer full of Proball. I quickly bought a case of it and I was back in business! No more barrel breaks just good paintball fun with no worries about breaks and having to clean my barrel every 5 minutes.
Proball has been VERY good to me this 2007 season. If I can help it (Field Paint Only Restrictions), I will never use anything but Proball. These balls mark well, and have a nice thick fill for no wiping purposes. If you are looking for a good brand of paintball for you, I would surely check out Proball and see if it works well for your marker.
