Does anyone have information or experience on the benefit (or detriment) of using CV spouts with buckets or bags or tubing drops into buckets? I've read the Proctor study on their benefit for their intended use in tubing systems, but assume the study didn't include anything about buckets. As an aside, can anyone explain why it is recommended to drill level when tapping with CV spouts (per the Leader website)? And as an aside to the aside, does everyone drill at a slight angle when using non-CV spouts or spiles?
