Windage tops, now there is a debateable subject. Now this is "MY PERSONAL OPINION" When Gary started making these rest back a number of years ago he talked about a windage top because some people just had to have one. He has yet to make one. I am from the school that by the time you screw around adjusting the top between the first and second shot the wind has gone somewhere else. I can bag squeeze a inch in an direction so tell me why I need a windage top. If I have to hold more then an inch, I don't want to touch that trigger. I have watch top shooters screw around with windage tops, adjust the windage, adjust the speed screw, go back to the windage screw, OH! now the elevation has changed, adjust that. Not knocking the procedure because I just watch and when he fires his first shot I can have my group done before he gets the second shot off. Now we are not talking about a Farley or Serb, that is a different deal. The movement is controlled by one stick. Just as a matter of interest, Tony uses a Farley, but up to about 3 or 4 years ago he was a bag squeezer, got arthritis in his left hand so had to go to a Farley type. Bottom line, "MY OPINION" windage tops cost more and do less and in actual fact will hurt your shooting.
