You may have to wait for a report on the X-Factor since they are just hitting the stores this week. Should be a good ball though.
As far as the Shock Trauma goes, I've heard nothing but good reports on them. Keep in mind, anyone's report on any ball is their opinion which doesn't mean that you will get the same results as them, good or bad. Your best bet would be to speak with your local
Pro Shop operator to see which ball and drilling options would be best suited for you.
I will tell you, from personal experience I am very happy with
Storm products. But again, that's only my opinion!!!!!!!! Whatever you choose, good luck.
