I grew up with IC in a short barrel. For quail I figured the only thing better was a cylinder bore and an even shorter barrel! As I went west, I tried a modified Invector plus choke tube in a Winchester a backbored, SX/2. I did not seem to miss. With pointed quail at 10 yards going out, or ruffed grouse and woodcock, I like the IC/C. with pheasants or prairie grouse where there are no trees, I like the modified.
