The specials are OK. They still have wobble in the arm, and don't really have the "feel", but much better than anything in that $ range. Best Floyd I've ever used is the Kahler Killer. Has ZERO arm wobble and has the lowest profile ever. Plus, the posts are backwards on these things. The knifeedge is on the post, which is really just a large machine screw. You never have to file your edges down, just go spend a few coins at the hardware store. Found two NOS a few months back. Just perfect too. $100 for both. Did I mention you can "whammy" the individual strings?
