I would agree for the most part. My personal preference is still to HPF the FX return around 150Hz, but it depends on the situation.

My previous suggestion was intended as a conservative approach. If I were dealing with feedback while mixing onstage, I would look for ways to eliminate low and high frequency transients that could cause or create the sense of instability in the mix.

It has been said before, but using feedback supressors or gates is a poor way to manage GBF…better to have all channels wide open and stable. Use those tools only as a last resort or for artistic preference (e.g. gate drums for a tighter mix…not to manage feedback).
