Trying to decide between the Tech Sight 100 with the short and long range leaves to the rear sight or the 200 sight with the elevaltion adjustment in the rear sight. Both sights use the same AR 15 front sight with elevation adjustment.

What change in impact between the short and long range leaves on the 100 sight. Are the opening in both apertures the same?

What advantage to the elevation capability of the 200 sight when the front sight is adjustable.

Any pros and cons to these sights?

Thanks
