Straight grip stocks are an anatomical disaster and simply do not work for me. And for other than posers I can't imagine anyone actually handicapping themselves by wanting one on a gun that is to be used.
AFA gripping goes, in my experience a gun shooting pigeon loads that is lightly gripped by either hand will be worthless for the second barrel. For me in practice that extends to any load and any two shot game. If controlling the gun constitutes man-handling and I don't know how it could not, then not man-handling the gun constitutes an uncontrolled gun. Proper (the operative term) shooting techniques may vary but controlling the gun is at the core of every one of them. That is not to say that some techniques are not crap.
JMO of course shoot however and whatever you like
