I say yes to BRs, & I like them just the way they are! IMO any half decent pilot should have no difficulty pulling them off, and there's a trade off in any race, as you lose ship energy each time you perform a BR leaving you more vunerable to weapons from other racers, or even crashes into track sides. The more BRs you use - the less weapons you can use, as you have to absorb to replace lost ship energy...or run the risk of being blown to bits!
