IMO the GOP is inexpensive protection for those days when mistakes are made.
Yaesu advises that the ALC interface is not required between the AL-80B and an FT-950.
Because the FT-950 cannot exceed 100 watts, you do not have to worry about ALC. However it is good practice to use a relay between the radio and the amplifier. Ameritron makes the ARB704 relay for this purpose.
