Depends on time and place.
If I've all day I'll load truck up with every bit of kit.
If I'm only out for a little while or can't get truck up to hide I'll take only a dozen flocked shells. But I never go out without taking my floaters! They bring height and movement to my pattern and IMO are the best bit of kit especially if used with a flapper.
You could take a shop full of equipment and not have a good day. LOCATION, LOCATION, LOCATION is the answer.
