FWIW I've heard that advice before - indeed, it was in the Cisco 
Enterprise/Campus core SRND at one point ("static link-aggs converge 
faster") - but I don't follow it any more.

Static link-aggs are a pain, because they come up unconditionally. This 
can cause things to explode horribly. Personally I would (do) use LACP 
everywhere these days, but would be interested to hear others thoughts.
