Final Notes:
Horizontal axis is fairly even around 100 degrees but a slight flare off axis pushes the 5-12khz range out a bit more. Horizontal pattern control is maintained down towards 800hz. The vertical edges don't have much of a roundover and you can see the mess the sharper transition makes, waist-banding in the 3-5khz range and pretty messy further off axis.
