Briley Ext LM is my usual "go to" choke in my M1, SBE and Extrema II for an all a rounder. The only real exception is on combo duck and goose trips where I don't absolutely expect them backwinging in the decoys then I use a patternmaster.

I have many others from Briley, Carlson and Trulock that I occasionally use but those 2 handle 95% of my choke needs.

As a note you will often see chokes labeled "duck" or "midrange", these are usually LM. Also "goose" or "extended range" are typically an IM/LF.
