Ive had my Guaranteed since its release and it is indeed smooth but consistent.
the heavy load particle makes this ball my ball of choice when the volume of oil is on the heavier side. what I like most about the ball is that it will let you know immediately that its time to put it away. not a ball that like to be forced into war so speak smile. Also had the xs power it was not the oiler the Guaranteed is for me
