For simplicity, Quantum already make two types of brackets, an L Bracket or a Flip Bracket which allows the flash to be rotated above the lens.
Both are OK and the handles are comfortable so one of those might do..
I tend to use a RRS WPP.. Like this WPF-QR although with the L bracket they work out quite expensive. (I love the L bracket for fitting to tripods, fitting radios, adding accessories, protecting camera body..)
