I shoot light mod for everything, except dove and sporting claysand then I shoot IC/light mod. cause I shoot my stackbarrel.... most folks would be fine with light mod or less choke....
honestly, switching chokes may be one of the most overrated parts of shotgunning...the change from IC to Mod isn't nearly as great as folks think (gives you roughly the same pattern 5 yards more distant)....
Colorado Luckydog you bring up a good point, if the gear is down you really don't demand a lot of your gun/shotshell.... I am not a fan of pass shooting, but I will take a long shot on abird hightailing it away from the blind after his buddies have met their demise
