I second what mike said. If you want movement you see, and are willing to pay for it, then an XXX Xtreme, Ace..if its a little less than heavy (IMO), or the new Vertigo would be the way to go. I love the Xtreme, the vertigo is looking real similar to me, but i don't have one so i can't comment. The Fear Factor is a heavy load particle, so its ideal look is straiter but the boards and a controlled finish. If you want a ball that will move and you can watch it, then get one of the others mentioned here. I don't think the Fear Factor is what you really want, judging by your comment about the Icon 300. They are similar balls, I would recomend a ball that shows you the move more. In other words if you want the move to be more distinct, and allow for more recovery then stay away from heavy particle balls. I learned my lesson the hard way (about $500 invested before i realized they weren't what i wanted), so i try to help others avoid my mistake.
