  The search for exclusive hadronic vector boson decays is an ongoing part of
the LHC programme where, to date, no such decays have been observed. In
addition to the intrinsic interest in the branching ratios, there is potential
for a measurement of the $W$ boson mass quite distinct from the usual methods.
The radiative decay modes offer good potential channels for this search;
however, we highlight three issues with it not previously discussed: particle
misidentification, partial reconstruction and the impact of interference with
QCD. These issues cause shifts in the peak position of tens or hundreds of
MeV/c$^2$.
