I had reasonably good results with Shock Absorber, pre-correct sizing. Now, alas, they don't make their awesome run bra in a big enough cup size for me. I have high hopes that this will change! Based on that experience, I'd definitely recommend it if it comes in your size!

FWIW, the Panache sports bra that I wear has convertible racerback straps. The hook is very durable and easy to fasten, and the bra is supportive enough that I only need the racerback for some tops, not for extra support.
