I had nothing but bad luck with brad points, so I researched them and found that the side spurs were the problem. They tend to follow the grain and veer off course. The point in the center is good, and bits designed to drill end grain have some sort of point in the center.
Since ditching the brads and going to a Morris Tools end grain bit I haven't wrecked a plug while through drilling. Even 8+"ers.
