Mr Old School,
I have, off and on, used quite a few visionary pieces. One thing I can vouch for is their performance. From the mildest one I had ( B/G CENTAUR ) to the most aggressive one I've owned ( CHARCOAL EXECUTIONER ), they do exactly what visionary says they will, and they do it with as much consistency as any ball I've used ( and I used to be a ball whore, having owned over 400 in the past years).
Now, as for which ones you would want? That depends on what reaction type you like most. They have balls capable of everything from down&in on dry (urethane OGRE) to hook the lane power (solid NEW BREED) and everything in between.
Oh yeah, their customer service is second to NONE, PERIOD!
