the sight I use is one I made specifically for the jug using the .target command..
basically its a circle.. and with the 8 guns set at convergences from 350-425 anything thing that falls within the circle will be hit with at least one pair from point blank to 800.
a little odd, but works perfect for me.. I tend to "overaim".. if I put just a single dot,, I wont squeeze the trigger till i get the dot exactly on target, which robs me of shots, too conservative. the circle FORCES me to be less anal about my aiming, if any part of the plane is in the circle. FIRE!
