I like it best if my opponent chops throttle, and either tries to saddle up on me or tries to roll with me in lag, so I'd recommend going with other options than that.
What makes the BRD the most challenging is an opponent who just refuses to play along (by just passing through, avoiding my guns, and reacquiring his perch for another attack). If he does that, I need to set it all up again, and again, burning E and time in the process.
Keep in mind, the guy using the BRD aggressively really doesn't want a drastic speed differential between himself and his attacker. What he wants instead is to be nearly as fast as his attacker, but with exaggerated closure. The defender regulates the closure by adjusting his angle-off, getting his attacker to approach from some amount of side angle.
The beauty of that tactic is that as he finishes his roll and places himself on your six, he's at almost the same speed as his attacker, which allows for a nice shot. If the attacker cuts speed, he sets himself up to fall into this trap. About the only thing he could do worse would be to attempt a rope as he finds himself out front of the defender.
There's a significant difference between the "defender" who uses the BRD defensively (by slowing down compared to his attacker), and the one who uses it aggressively to snatch his attackers scalp (by keeping his speed up in relation to his attacker). In the first case, slowing your attack, rolling along in lag, etc might work quite well. In the second case though, that "defender" probably has a big smile on his face as he watches you out of his high rear view, then high side-rear, then side rear, then dropping below/behind his tail, only to pop out in his high opposite-side six, then directly below him as he's inverted, then in his up-front view following a path right through his cross-hairs (but he'll shoot you before you get to his cross-hairs).
