Hoof,
I consider full choke a handicap at sporting clays as well. The only time I shoot them is when I want to enter an event at a vintage shoot, for example the 16 ga. event, and the only vintage gun I have in 16 ga. is an Elsie with extra full chokes. my "go-to" chokes are mod/mod., but occasionally use less when it fits the course better.
It seems to me that as competitive s.c. shooters improve many of them graduate toward tighter chokes. There is a great confidence level that comes with turning clays into puff-balls with tighter chokes.
Different chokes for different fo'kes.
