In general, ALC between an amp and a rig is a recipe for clicks and 
splatter. Most authorities advise against using it. This is not new -- 
it's in the manual for Ten Tec legal limit amps from the late '70s and 
for every amp I've owned since.

If it is used, it should be set for well above normal output power so 
that it only kicks in to reduce drive when something breaks in the 
antenna system or the operator experiences brain cramp and transmits 
into the wrong antenna. :) And good solid state amps are well enough 
protected that they do that without ALC.
