Infinity Theory gives me a reaction in my bag like no other.The infinity theory i drilled allows me to clean the front part of the lane really well for a highend asymetrical ball i my bag with nice controoled backend reaction,nothing to over under.Also with great coverstock they put on this ball the insight hybrid reactive coverstock allows me to also read midlane recation better.Cover stock in very east to alter if need be.choice of colour great on this ball.
