I like my 28"/28ga chokes just fine with their unusually heavy constriction. They toss some good patterns, out pretty far, with a 7/8 oz Fiocci Golden Pheasant #5 load and the Rem STS #8 load. I have taken some farm raised chukar and pheasant with it over my Lab. I have no reason to open them up. Maybe if I had a pointy.
