I have no problem with opening chokes in non collector guns. Cylinder or near cylinder bores have always produced the best patterns for me at the ranges I normally shoot, which is seldom over 30 yards. Modern shot cups provide their own "choke" that the old timers didn't have the benefit of. A couple of my English guns are factory bored cylinder and full, which certainly gives a wide latitude for variable shots. I like them. To each their own.
