like others have said the flatline is very picky with what paint it needs.....alot of people use high end paint like marbellizers, or evil...for us who cant afford the high end paint, i found that recon, that you buy from wally world works really good. I had been using visible impact, almost every one broke in my flatline, i then got about 500 recon from a friend and not one of them broke....they flew straight...so i would suggest recon myself

orgin paintball works well with the flat line on the 98 but i am no sure on the a5 flat line

Beast paintballs are rocking my world, and my a5 with rt and flatline, even in the cold rainy winter time, I like the beast, two cases shot so far not even one break. now if they would just ship it to Canada.

got to add beast to that list, the beast loves the flatline, I was shooting at 280 fps, no breaks in the cold too.
