Zombies..
Is the Hara Pro 4 that much more worth it. I have the normal pro 4 but have a chance to pick up a hara edition for a really good price. Or should I maybe just hold out for the Cyclone to be released?

pivot block screw could be bent as sell. must of been a hard frontal impact to move the pivot blocks back.
