I still own a very nice el nino original that i got used from kendra gaines, ball backends with anything made today. You are correct on the reactor coverstock thoughts it is a very versitile cover, it combats the activator covers and give storms ball a whole new look. I was really liking the dynothane balls made by storm now with the change to columbia i am up in the air about there little company. I will try there next release out and see where i stand, i also like rotogrip alot if you have tried the horizon and the epic battle you will understand my liking them. Tweaked storm covers that high diffs that push down the lane well and backend very hard, i shoot good numbers when i use these and some of the dynothane balls.
I got a gem from my proshop the ball is called x-factor x35 a particle pearl accutread cover called ultimate accutread pearl, these ball has the original x-factor core and the new cover. Clears the heads with ease and the mid lane and backend are very crisp on anything from light medium on up. If you can get find one of these i would highly recommend this ball to all.
