That about sums it up..yes. I wouldn't worry too much about it though. I've never seen a bst in any of the more "professional" groups I've done VW with. Saw pup once or twice, but never a bst. Maybe bst could get into a shout group for some of the lower tiers. Any of the harder ones though bst just isn't practical. As you suggested bst is viewed as "dead weight" for a variety of reasons.
