The problem with a quartering to shot is the steeper the angle the more bone is in the way.
Slight quartering to? Probably Ok, but not ideal.
Quartering away shot is much preferred anyday and much more room for error. Yeah, you can screw any shot up, but I don't think there are many people who would argue that a quartering away shot is much preferred and has much more room for error.
Most of the time guys take a quartering to shot a little patience would have yielded them a much better shot.
