Bright Fills, Orange/yellows are always round-non greasy, Good Balls, Fly straight and far
Purple/Aquas are always greasy and flat spots / Not enough air in bags when manufactured
I think these are great balls. They are usually around 55 or so. I only recommend the Orange/Yellows. These are always the better of the batches, always round and not greasy. Every bag of Purple/Aqaus I have seen have flat spots and are greasy. I dont reccomend the Purple/Aqaus. Theseballs perform great in my Flatline and my friends Spyder AMG. They are a great, high performance ball sold cheap.
I recommend buying these. They perform like Evils(so I hear) and are alot cheaper. The Orange/Yellows are the best and avoid the Purple/Aquas. Buy these balls, you wont regret it.
