Ball is great for short, dry or big over-under conditions. Don't know the rg dif but i can get my to flare 1 1.5 in. I still have 2 of them that i use for second shift in my travel league and i have even used one on the Viper pattern in my PBA league. It didn't over react on the back and had plenty of punch until we carried the oil down then i could go to a reactive. Hope this helps.
