My cyclone is pretty strong, strong cover anyways
300 series from Track: I have all 3 balls
300c is a bit over/under - not consistent would be a better description
300t - weakest of the group, mine is pin down, great for the lighter patterns
300a - newest one for me, have 2" pin-pap layout done by Mitch B. ball has great push and very even arcing, hits the pocket well
all 3 take to surface changes very well
